From the Brookhaven National Laboratory: Yearlong MAGIC Climate Study Launches
Climate instruments mounted aboard the Horizon Spirit container ship begin taking data
The Horizon Spirit makes the round trip between Los Angeles and Hawaii every two weeks.
UPTON, NY — A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by U.S. Department of Energy (DOE) scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data today for a yearlong mission aimed at improving the representation of clouds in climate models. The study, a collaborative effort between DOE’s Atmospheric Radiation Measurement (ARM) program Climate Research Facility and Horizon Lines, marks the first official marine deployment of the second ARM Mobile Facility, AMF2, and is likely the most elaborate climate study ever mounted aboard a commercial vessel.
Brookhaven scientist Ernie Lewis and one of the mobile SeaTainer units now installed aboard the Horizon Spirit, a 272-meter cargo ship that will take atmospheric measurements during a yearlong cloud/climate study.
“We are very grateful to Horizon Lines for giving us the opportunity to install our research equipment aboard the Horizon Spirit,” said lead investigator Ernie Lewis, an atmospheric scientist at DOE’s Brookhaven National Laboratory. The Horizon Spirit makes a roundtrip journey from Los Angeles to Hawaii every two weeks, which allows for repeated measurements over the same transect at different seasons.
“Collecting data on a wide range of atmospheric conditions over an entire year, including the transitions among cloud types along this particular route, will give us a large amount of data to help refine and validate models of Earth’s climate,” Lewis said.
The project—dubbed MAGIC, for the Marine ARM GPCI Investigation of Clouds, where GPCI is a project comparing results from the major climate models—will take place through September 2013.

“We are excited to deploy the AMF2 sensors and the infrastructure that supports them on the Horizon Spirit. This represents the culmination of four years of hard work in designing, building and preparing to deploy aboard an ocean going vessel,” said AMF2 Technical Operations Manager Michael Ritsche, an atmospheric scientist at DOE’s Argonne National Laboratory.
Clouds and climate
Low marine boundary layer clouds over the ocean exert a large influence on Earth’s climate through reflection of sunlight and by mediating interactions between the atmosphere and the ocean, Lewis explained. However, global climate models have difficulty accurately representing these clouds and the transitions among their different types. Extensive data collection from a marine environment with variable cloud cover could significantly improve these models.
Horizon Spirit’s route from Los Angeles to Hawaii (dashed line) lies adjacent to the GPCI transect that is used to compare climate models (solid line), which also contains specific locations used for other modeling efforts (labeled points). The color scale representing the annual average percentage of low-level cloud cover over the region shows that the route is ideal for assessing the effects of changing cloud conditions.
Horizon Spirit’s route crosses just such a region, making it ideal for assessing the effects of changing cloud conditions. This region is important to a wide range of climate models included in the GPCI project.
“Horizon Spirit’s route from Los Angeles to Honolulu lies almost on top of the GPCI line, providing a great opportunity for extensive data collection,” said Lewis. “We approached Horizon about working together on this project with the idea that our equipment could be installed on the ship with no disruption of their ordinary operations.”
“Horizon Lines is happy to cooperate in the year-long MAGIC project to improve climate modeling,” said Pete Strohla, Vice President of Operating Services at Horizon Lines. “Our hope is that better understanding of climate change will facilitate more accurate weather forecasting, which in turn will help our industry plan safer and more fuel-efficient vessel routes.”

A group from Argonne in charge of the deployment has spent the past nine months preparing the instruments and optimizing their performance for shipboard data collection. Many instruments, including an aerosol observing system developed by Brookhaven scientists, are housed in three modified 20-foot SeaTainer cargo containers designed for mobile deployment. Other instruments include radars that are mounted to tables designed to maintain stable “vision” despite the inherent rolling of the ship’s deck as it plies the waves. All of these instruments were installed aboard the Horizon Spirit while it was in port in Los Angeles in September, with final preparations made while en route to Hawaii and back.
“Altogether, the AMF2 comprises a suite of instruments to measure properties of clouds and precipitation, aerosols, and infrared, visible, and ultraviolet light, as well as meteorological and oceanographic conditions,” Lewis said. “These ship-based measurements can provide much more detailed information than can be determined from satellites, and these data will prove a valuable addition to other measurements that have been made in marine conditions, albeit for much shorter periods, for many of these quantities.”
The science team—which includes researchers from DOE’s Lawrence Livermore National Laboratory in addition to Brookhaven, as well as collaborators from NASA, Stony Brook University, and a range of other universities and private consultants—is anxiously anticipating the data that will arise from this endeavor.
“In the end, these data will greatly enhance our understanding of clouds, aerosols, Earth’s energy and water balance, and the interactions among them in the marine environment, providing an unequalled dataset for evaluating and improving climate models,” said Lewis. “Our data, which will be placed in the ARM Data Archive, will be made available to anyone who is interested.”

Rubbish.
To do it properly you need solar powered platforms equally space through out the globe where every Line of Longitude intersects every line Lattitude.Unfortunately Pirates will be stealing them for scrap
This survey ship going anywhere near Somalia.
Also needs to be a Sail ship to avoid interference from its Engines Heat and Exhaust.
And it can only monitor in Calm seas where the weather patterns are stable
Just use infra red satellites Cheaper and they are already up there.

> Some fun with numbers. From the weather network. Vancouver monthly record snowfall set in Oct 31, 1984.
Please don’t hijack a post’s discussion with off topic information early in its life, and please make it clear that you are doing so. I suspect a number of non-North Americans don’t realize that Vancouver is nowhere near the Hawaii to Los Angeles shipping corridor.
Your comments would have been fine on the next Open Thread.

The 30 year metric is generally used to log climate as it changes, a very different process than learning about how weather systems behave. There are cyclic processes to be studied at several periods. Are you suggesting this project be abandoned because it’s not looking at a 200 year solar cycle?
A number of processes that affect clouds behave the same around the world, a number are fairly local. The post makes it clear that this transect is already being studied by satellite and models, so it’s quite sensible that detailed local information be collected for ground truth if nothing else. Sure, a broader network would be nice, but this seems like a good starting point to me and data collected here could provide good guidance for similar efforts elsewhere.
This also seems like a very good transect to study given the change in low level cloudiness along its length. Note also that low level cloudiness in eastern ocean basins are the areas of most interest in Svenmark’s hypothesis so this data should be extremely interesting to folks studying that.
ferdberple, you aren’t aware of the traditional Thanksgiving Snow Festival in Vancouver? 1984 was the first year in living memory that it had to be cancelled.
Seriously, although this experiment seems massively expensive, and it is only a sample of one, the idea is good. Maybe if they could make it less expensive and equip many more ships …
There may well be a worse method to gather “meteorological and atmospheric” measurements from the open ocean than this. But I honestly can’t think of what that method might be.

Shouldn’t they have done this BEFORE making all those scary predictions?
“…a yearlong mission aimed at improving the representation of clouds in climate models.”
Since they currently have no idea how to represent clouds in their Playstation simulations, I suppose any addition of knowledge is an improvement. Unless, of course, that new knowledge raises more questions than answers — always a possibility.
Back when I was a radio operator at sea (1978-1984) it was a daily practice to send OBS reports (weather observations) from every vessel in the (BP Shipping) fleet and many other companies did the same. Wasn’t THAT information of any use? The system is AFAIK still in operation.
From 21° N to 34° N – that’s isn’t much latitude. They WILL miss a lot!
Anybody see mention of a neutron counter or other particle detector? I may have missed it. They did provide a state-of-the art aerosol instrument.
This is a good thing. We don’t fully understand the complexity of cloud effects on weather, much less climate. It is a cheaper way than operating dedicated research vessels. However, it will not provide much of the data that is needed to develope a good three dimensional model. They now need to contract with a airline that regularly travels the same route, faster and more often. I strongly suspect that clouds are controlling both the concentration and distribution of CO2. I think that such a three dimensional study would give us some answers.
Like other’s: I have immediate doubts about a container mounted sensors somewhere close to a very large diesel engine (or Steam, from the design that’s an older ship but I might be wrong, intra US trade tends to use smaller older ships as it’s gruesomely un-economical to build large commercial ships in the US) but one hopes the scientists and engineers involved have thought about it.
Sounds like a fascinating experiment. Where on the ship are the experiment’s containers located? How do they prevent them from being accidentally offloaded? Are they self-contained or are they drawing ship’s power? I still have a lot of questions, but it sounds very interesting. I hope something useful comes out of it and something similar can be done with other container ships on other routes around the world.
The ship in the picture above is not the “Horizon Spirit”. It looks like the “Horizon Producer” or her sister the “Horizon Consumer”. The “Spirit” is of another design and 50m longer.
Aren’t there satellites already providing whole Earth data on clouds?

Can’t clouds be studied better by satellites? Clouds between Hawaii and CA must show up better on satellite views than a ship going back and forth.
Great – an L.A.-Hawaii track.
Stopovers in Hawaii while the ship loads and unloads. Scientists need to travel with the equipment, just to make sure there are no problems.
I’m sure the schedule’s already been decided – kinda like a time-share.
