Hi Daphne, I put a compressed file (FOG.zip) of fog product AREA files out on our anonymous FTP server for you to grab: machine: ftp.unidata.ucar.edu user: anonymous pass: address@hidden directory: pub/mcidas/FsuFog file: FOG.zip Each file is a product created from the combination of the IR (10.7 um) and IRS (3.9 um) GOES-East channels using the formula: brit = 150 + 10*(T10.7-T3.9) The calibration for converting brightness back into delta(T[K]) has been included in the AREA file, so one can easily interrogate the images for values at user-selected points using McIDAS-X, McIDAS-V or the IDV. I have not (yet) used your list of stations/lat,lons to generate CSV files of delta(T[K])s as a function of date/time, but I could do this if you want me to. Please let me know if you have any questions about how the FOG AREA files were created, or if you see anything that looks amiss.
