Level 2 BRF Extension for the misr_envi tool Installation Instructions Copy the IDL program files (those with the .pro extension) into the ENVI save_add directory. This directory is directly under the ENVI directory in your ENVI installation, e.g. for unix /usr/local/rsi/idl_6.1/products/envi_4.1/save_add or for Windows C:\RSI\IDL61\products\ENVI41\save_add In order to invoke the program from the ENVI file menu, add the line 3 {MISR L2 for BRF} {not used} {misr_envi_level2brf} into your existing envi.men file in the ENVI menu directory under the EOS entries. That section of the menu file should look like 2 {EOS} 3 {ASTER 1A/1B} {open aster} {envi_menu_event} 3 {MISR L1B2} {not used} {misr_envi} 3 {MISR L2 for BRF} {not used} {misr_envi_level2brf} 3 {MODIS 1B} {open modis} {envi_menu_event} Then use that menu item to open the Level 2 file. The program will then execute in a manner similar to that shown in the misr_envi tool User's Guide.
