MONORTM_v4.2

An error related to the print-out of total optical depths in the MONORTM.OUT file was corrected.

MONORTM_v4.1

Code is now using MT_CKD_2.4 continuum, which includes significant updates to the self- and foreign-broadened water vapor continuum in the range 0 to 600 cm-1 (0 to 18 THz), based on new analyses of ARM measurements in the microwave and far-IR regions. (Payne et al., manuscript in preparation, Delamere et al., manuscript in preparation)
An error related to calculations for multiple profiles was corrected.
Code has been modified to pass optical depth arrays between subroutines as arguments in order to improve modularity of the Monochromatic Optical Depth Model (MODM) module. In addition, the IOD option may now be used as a flag to output layer optical depths to ascii files.

MONORTM_v4.0

Code has been updated to allow monochromatic calculations at frequencies beyond the microwave region. These updates include the implementation of CO2 line coupling and the option to include cross-section molecules. Format of output files has been modified to accommodate this change.
Calculation of the total internal partition sum has been updated to be consistent with the calculation in LBLRTM.
MonoRTM now uses MT_CKD_2.1 continuum (previously was using CDK_2.4).
An error in the nitrogen continuum has been corrected.
The INP option has been replaced by the use of IATM=1 or IATM=0 (consistent with LBLRTM). A stand-alone IDL program is provided to convert ARM netCDF profiles into MONORTM input format.

MONORTM_v3.3

directory structure has been changed to make it more consistent with LBLRTM
the 22GHz and the 183GHz water vapor lines have been updated (Payne et al, 2008)
the 325 GHz water vapor line has been updated to reflect CRB calculations by Gamache
the 380 GHz water vapor line has been updated according to measurements by Koshelev et al (2007)
corrected error in surface reflectance code
updated limb radiative transfer code

MONORTM_v3.0

code has been updated to allow scaling of profiles
spectral line file has been modified to include new oxygen line widths and line-coupling coefficients from Tretyakov et al (2005)
more lines in the spectral line file are now included in the fast option, to increase accuracy at higher frequencies and lower water vapor amounts

MONORTM_v2.20

code has been restructured and made more robust
new makefiles allow for the creation of single and double precision code on SGIs and on MacOSX

MONORTM_v2.12

a new LBLATM module has been added, which is consistent with the LBLATM module currently used by LBLRTM
several minor coding inconsistencies, which led to compilation errors under some compilers, have been eliminated

MONORTM_v2.11

O2 line coupling parameters have been modified to yield significantly better agreement with MWRP measurements in the 50-60 GHz range
code output contains more detailed information on the current version of the software and the spectral lines file
