urban heat islands: data documentation, make maps clearer
Documentation should report the resolution of the MODIS data
Maps should say "summer" more prominently, and not distinguish between -1 to 0 and 0 to 1 without a middle category reflecting the precision of the estimates.
I was also somewhat confused by the term "average daytime maximum (1:30 p.m. overpass)" and its nighttime analog - over what samples are the maxima and averages calculated? It is clearly not the case that 1:30 temperatures are always the daytime maximum.
