>From: Jimmy Adegoke <address@hidden> >Organization: Penn State >Keywords: 200006271916.e5RJGgT14015 McIDAS GOES-8 VIS calibration Jimmy, On June 27 you requested information on finding the calibration constants for converting GOES-8 VIS brightness to albedo: >I'm need to find the calibration constants for converting GOES 8 VIS >brightness to albedo. The equation I'm using for the conversion is: > >A = (aB*B + b)/IcosE > >where a, b and I are calibration constants > B = brightness value > E = solar elevation angle > >I have the calibration constants for GOES 7. They are 0.00539 W/meter sq. >for a, -2.67 W/meter sq. for b and 336 W/meter sq. for I, respectively. >Can someone kindly point me to where I can get similar constants for >GOES 8 ? > >Greatful. I just received an additional web page inforation from SSEC on this subject: Awhile back I think you were asking about GOES calibration tables. Here is the page I was looking for: http://orbit-net.nesdis.noaa.gov/arad/fpdt/goescal/goescal.html I hope that this helps. Tom Yoksas
