Request for Heat Index to be Calcuated at AWOS Sites

Post by geophi »

Hi Tim,

Enhancement - While wind chill is calculated for both ASOS and AWOS sites, heat index is not calculated for AWOS sites, actually maybe any MTR that has AUTO text preceding the wind. There are lots of areas where there is a large distance between ASOS sites, and having it calculated for AWOS sites as well would be useful for any analysis or situational awareness. I'm not sure of the reason for this omission. Certainly the dewpoint at AWOS sites can be more frequently wonky than at ASOS sites, but it would be nice to have the option to plot/analyze the HI at all MTR sites.

See below for an example where an ASOS site (KCLL) and AWOS site (KCFD) are nearby, with the same plotted T and Td, but HI is only plotted for the ASOS site KCLL which has a HI of 87. The graphic below that shows a plotted map from the Central Plains with numerous AWOS sites without any HI.

KCFD 301955Z AUTO 00000KT 10SM CLR 27/17 A3014 RMK AO2 T02740174
KCLL 301953Z 00000KT 10SM CLR 28/17 A3012 RMK AO2 SLP195 T02780172
