In-Band
Solar Energy Comparisons. Channel filter function, normalized filtered solar response plots for
channels 1, 2 and 3a. Clicking on Thuillier (CEOS) and Kurucz (MODTRAN) integrated solar amounts
shows channel filter functions. Neckel and Labs data is taken from the AVHRR
POD-Guide and the AVHRR KLM-Guide
