This graph got rather buried at the end of a long explanatory post showing the twists and turns I had to take to get the data. I think it needs front and center exposure, so I’m putting it here.
It is rather hot over asphalt. It’s even warmer when the temperature sensor malfunctions and creates a string of new record highs that the NWS does not see fit to remove from the records.
Note when the highs (Tmax) converged for the first time this month to within one degree.
The data from the two Oahu stations, 3.9 miles apart on the south shore. When plotted side by side, was telling. I marked missing data, the record high events, and when the ASOS was repaired.
Which station is more representative of the climate of Oahu? One is at an airport, one is not. Which station is doing a more accurate job of depicting climate? Details here.
