Get the distribution Here is the most recent version 1.6-beta from March 4, 2011 (“groundhog release”). The new version has several new features compared to the last release 1.5-beta, see [Newsletter 13]. text/html 2011-11-25T08:49:27+01:00 arve http://www.libradtran.org/doku.php?id=known_bugs&rev=1322207367&do=diff libRadtran doesn't compile Solution: When compiling uvspec, please make sure that you have all required compilers and tools installed, see Download. For the newer versions of Linux, some of the standard tools are no longer installed by default (as modern users don't want to fiddle around with such ugly things as compilers etc). One particular example is Flex - The Fast Lexical Analyzer. It is usually available for all flavours of Linux, under Mac, and for cygwin, but not necessarily installed b… text/html 2011-11-25T08:48:43+01:00 arve http://www.libradtran.org/doku.php?id=faq&rev=1322207323&do=diff How serious are serious differences reported by "make check"? They are usually not as serious as it sounds. We haven't had a case where libRadtran worked on one computer and produced really wrong results on another. However, radiative transfer equation solvers like disort are numerical methods which are affected by the limited numerical precions of processors, and these differ from processor to processor and sometimes even from compiler to compiler. Usually, large differences occur for small n… text/html 2011-11-20T15:03:49+01:00 arve http://www.libradtran.org/doku.php?id=contact&rev=1321797829&do=diff In case of questions about libRadtran, or to report a bug, or to offer help please contact one of the following.

That way, each adressee at least knows that the other ones were asked as well.

Download from UNIDATA and installation following the INSTALL guide seem to work fine (make check is happy), but neither binaries nor library files are written to the ”/usr/local” directory nor any other usual path as far as I could see. text/html 2011-09-14T11:16:30+01:00 admin http://www.libradtran.org/doku.php?id=previous_versions&rev=1315991790&do=diff text/html 2011-09-14T11:15:51+01:00 admin http://www.libradtran.org/doku.php?id=lbl2od&rev=1315991751&do=diff Python scripts for Computational ATmospheric Spectroscopy From Hitran/Geisa to Molecular Optical Depths * extract (select) lines of a certain molecule (and isotope) and/or wavenumber range from line parameter database * lbl2od computation of line-by-line optical depth due to molecular absorption text/html 2011-08-11T17:35:30+01:00 admin http://www.libradtran.org/doku.php?id=user_area:water_reflectivity&rev=1313076930&do=diff Did you ever wonder where the blue ocean gets its color from? Of course you can answer this question with libRadtran! All you need to do is calculate radiances at TOA for a number of angles (umu,phi) using output rgb to calculate colors instead of radiances, and plot the data. The ocean surface is treated with the parameterization by Cox and Munk [1954] and Nakajima et al.
