ABI Bands as of October 15, 2003. The first 16 bands are set as defined in the PoRD. The PoRD can be found on the web on the ABI documentation page: http://goes2.gsfc.nasa.gov/abihome.htm Bands 17-21 are experimental. They are included in the order in which they were experimented with. Bands 17 and 21 are variations of band 12. Bands 18, 19, and 20 are variations of bands 8, 9, and 10. These experimental bands are included so they can be tested for scientific merit over the currently proposed bands. The spectral response functions are named for a Gaussian Boxcar Hybrid function. They are created using code from Mike Griffin at MIT Lincoln Labs. The curve is gaussian, forced to go through the 50% points (lower and upper wavelengths) and the top of the curve is flattened out like a boxcar function, hence the name. v1 Stands for version 1 (the current version as of October 15, 2003). Channel numbers are not officially stated in the PoRD, but CIMSS has assumed a numbering convention for ease of use in software - the bands are numbered by increasing central wavelength (same convention has used on the current GOES series of imagers, but opposite as the current sounder) for the first (official) 16 bands. 50% 50% Band Lower Upper Center Filename No Waveln Waveln Waveln 01 0.45 0.49 0.47 ABI16_GBHv1_SRF_CH01.TXT 02 0.59 0.69 0.64 ABI16_GBHv1_SRF_CH02.TXT 03 0.84 0.88 0.86 ABI16_GBHv1_SRF_CH03.TXT 04 1.365 1.395 1.38 ABI16_GBHv1_SRF_CH04.TXT 05 1.58 1.64 1.61 ABI16_GBHv1_SRF_CH05.TXT 06 2.235 2.285 2.26 ABI16_GBHv1_SRF_CH06.TXT 07 3.8 4.0 3.9 ABI16_GBHv1_SRF_CH07.TXT 08 5.7 6.6 6.15 ABI16_GBHv1_SRF_CH08.TXT 09 6.8 7.2 7.0 ABI16_GBHv1_SRF_CH09.TXT 10 7.3 7.5 7.4 ABI16_GBHv1_SRF_CH10.TXT 11 8.3 8.7 8.5 ABI16_GBHv1_SRF_CH11.TXT 12 9.65 9.8 9.73 ABI16_GBHv1_SRF_CH12.TXT 13 10.1 10.6 10.35 ABI16_GBHv1_SRF_CH13.TXT 14 10.8 11.6 11.2 ABI16_GBHv1_SRF_CH14.TXT 15 11.8 12.8 12.3 ABI16_GBHv1_SRF_CH15.TXT 16 13.0 13.6 13.3 ABI16_GBHv1_SRF_CH16.TXT 17 9.42 9.8 9.61 ABI16_GBHv1_SRF_CH17.TXT 18 5.77 6.6 6.19 ABI16_GBHv1_SRF_CH18.TXT 19 6.75 7.15 6.95 ABI16_GBHv1_SRF_CH19.TXT 20 7.24 7.44 7.34 ABI16_GBHv1_SRF_CH20.TXT 21 9.6 9.8 9.7 ABI16_GBHv1_SRF_CH21.TXT The files contain 2 columns. Column 1 is wavenumber, column 2 is relative response (response is from 0 to 1). There are no headers on the files.
