atmos 3.0

The most up-to-date information related to atmos 3.0 are collected here due to constantly increasing interest to MASS/DIMM processing software...

Obtaining the software

atmos 3.0 is still beta, so the latest version is 2.97.12 (there is also 2.98.x branch which absorbs new features)

Check also our RPM-repositories (and maybe you'll find there ready RPM packages): http://curl.sai.msu.ru/repositories/mass/

Please remember that you are free to do everything you want with the source code under GNU GPLv3 conditions.

You need the following pre requirements (check that appropriate -devel packages are installed in your system before compilation):

Then try

If anything isn't ok, please feel free to ask questions and report problems.

How to concatenate MASS and DIMM files for join processing: ( grep ^[dP#] 090925-dimm.stm; cat 090925-mass.stm ) | sort -k2,3 -s > 090925-massdimm.stm
How to process: Feed mass.stm (that was produced by the new turbina software) into atmos and read its output: ./atmos < 090925-mass.stm > 090925-mass.out
How to process the data which are produced by turbina 2.x?: You need this script to convert your .stm and .mass files into the new format. It can work as a pipe-filter, so you don't need to store additional files for reprocessing.
Where are patched rescripts?: They are here: remass.tar.gz
