US-Uranium-aquifers

The next big worry: Claim of major U.S. aquifers contaminated by Uranium – but is it really a problem to health?

Study: 2 major US aquifers contaminated by natural uranium Naturally occurring uranium is being mobilized by farm-related pollution From the University of Nebraska, Lincoln. Nearly 2 million people throughout the Great Plains and California above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of…

Silver Ants

Guest Post by Willis Eschenbach I stumbled across a lovely article about the Saharan silver ant over at phys.org. These ants have special hairs that reflect strongly in the visual and radiate strongly in the infrared. They show a photo of the ant hairs under a couple different amounts of magnification: Figure 1. Photograph from the phys.org…

The Desert Finder

Guest Post by Willis Eschenbach Despite doing lots of research and investigations over the last few weeks, I’ve written little. Well, actually, I’ve published little, although I’ve written a lot. But I didn’t publish what I’d done, there was no wonder in it, no awe. So I tossed it all out and started “simply messing…

The CERES Calculated Surface Datasets

Guest Post by Willis Eschenbach The CERES dataset is satellite data that is based on radiation measurements made from low earth orbit. The CERES data has two parts. The first part is observational data, measurements of downwelling and upwelling solar radiation and of upwelling longwave radiation. It is usually referred as the CERES “top-of-atmosphere” data.…

A First Look At SURFRAD

Guest Post by Willis Eschenbach Since the late Nineties the US has had seven industrial-strength stations that measure a variety of climate variables every minute, 24/7. These are called “SURFRAD” stations. As a data junkie I’ve been wanting to look at their results for a while … but the data is in an ugly format. They have…

A Modtran Mystery

Guest Post by Willis Eschenbach I’ve been messing about with the “Modtran” online calculator for atmospheric absorption. It’s called “Modtran” because it is a MODerate resolution program to calculate atmospheric infrared absorption written in ForTRAN, which calculates the result for each 1 cm-1 wide band of the wavenumber across the spectrum. Not quite a “line-by-line” calculation, but…
