Streamer
Known Problems

General Problems

• Negative radiances - This has been a "problem" since the beginning. It is NOT a bug, just one of the difficulties in dealing with a complex system. You can get negative radiances when the energy level is very low overall (e.g., at 3.7 microns), and when the cloud phase function (represented by the asymmetry parameter) is poorly approximated by the Henyey-Greenstein function. The easiest solution is to increase the number of Legendre coefficients and possibly the number of streams. Note, however, that the problem cannot always be solved this way.

Platform-Specific Problems

• Watcom Fortran - This version of Fortran does not allow character strings of length 2400 as used in 'replace.f' and 'print.f'. Reducing the size of these strings "fixes" the problem, but you will not be able to have as many continuation lines in $PRINT and $REPLACE statements.
  
  
• VMS - VMS does not have the 'getarg' function, which affects passing the Streamer input file name as a command line argument. See the User's Guide for a work-around.
