Weather Charts

New Covid-19 forecasts: Per the US DHS, the half-life of the SARS-CoV-2 virus in open air is inversely correlated to UV radiation, relative humidity, and temperature. Choose those graphs below for a rough estimate. UV radiation (sunlight) matters a lot (high UV is good), relative humidity and temperature matter less, but for both, high values are good. [1]
Example 1: High UV, 30C, RH 70% -> half life of 1.9 minutes.
Example 2: Low UV, 10C, RH 20% -> half life of 107 minutes. Two orders of magnitude worse.
