Version 5.4 The continuum was updated to MT_CKD_3.2, which has new self continnum coefficients in window regions for wavenumbers greater than 2000 cm-1 and updated self continuum temperature dependence from 1800-3500 cm-1 (E.J. Mlawer, M.J. Alvarado, K.E. Cady-Pereira) Corrected TKC coeffs in the CloudOptProperties routine. K.E. Cady-Pereira, August 2017 **************************************************************** Version 5.3 The continuum has been updated to MT_CKD v3.0, which included modifications to the H2O foreign continuum from 0-600 cm-1 and the self continuum in the microwave that resulted from an analysis of measurements taken at the ARM RHUBC-II campaign and a re-analysis of RHUBC-I measurements. (E.J. Mlawer, D.D. Turner, S.N. Paine, V.H. Payne) Eli Mlawer, November 2016 **************************************************************** Version 5.2 The model for computing cloud liquid water absorption coefficients was replaced. Prior versions used the model from Liebe, Hufford, and Manabe (1991). This version uses a new model from Turner, Kneifel, and Cadeddu (2015). The differences are small for temperatures above 0 deg C with frequencies below about 60 GHz. Differences may be large at higher frequencies and very large at lower temperatures. The new and old models now reside in a new module in CloudOptProp.f90. Subroutine modm uses a generic interface to obtain the cloud liquid water optical depth from one of the models in CloudOptProp, and that interface points to the new model by default. Alan Lipton, AER, June 2015 Fixed bug in reading TAPE3 Karen Cady-Pereira, AER, August 2015 **************************************************************** Version 5.1 Testing MonoRTM_v5.0 desmonstrated that the added capablity functionality to handle species specific line broadening coefficients significacntly slows the code down. An additional input parameter (IBRD) was added to make using these broadening coefficients optional. CLW was initialized in monortm.f90, to avoid NaNs occuring in some compilers. lnfl_mod.90 now reads the spectral lines file (TAPE3) starting at 25 cm-1 to the left of the first requested spectral point, or the beginning of the TAPE3, if the requested point is within 25 cm-1 of the beginning. **************************************************************** Version 5.0 The code was significantly restructured, new capabilities were added, and the spectroscopy was upgraded. * Restructuring (K. Cady-Pereira, G. Uymin, A. Lipton) - All routines except tips_2003.f are now f90. - The code's spectroscopic line input structure and atmospheric profiling code were made more consistent with LBLRTM. Line parameters are now read from a binary TAPE3 file (as in LBLRTM) produced with MonoLNFL, which is now included in the MonoRTM package. - The code to read in and store the spectroscopic data was removed from modm and is in a separate module: lnfl_mod.f90 - The RT codes are also in a new module: RTMmono.f - Physical constants are all declared in one module, PhysConstants.f90, which also provides routines to access the values; geophysical parameters in another similar module, PlanetEarth.f90. * Additional capabilities - The capability to utilize a speed-dependent Voigt line shape has been added using the approach of Boone et al. (2007; 2011) (M. Alvarado). - The spectral region about line center in which the detailed Humlicek (1982) method is used to compute the line shape has been extended to provide greater accuracy (M. Alvarado, E. Mlawer, G. Villanueva). - The method to compute path lengths in the code's atmospheric module was changed to provide greater stability for cases with exceptionally high rates of change of refractive index with height (M. Alvarado, E. Mlawer, D. Turner, N. Miller) - A number of new input and output options, including optional netcdf output with spectral layer optical depths, have been added. (K. Cady-Pereira, D. Berthiaume) - Mixing ratio inputs are now allowed for IATM=0 (K. Cady-Pereira, J. Delamere) - The capability to utilize available line broadening coefficients (width, temperature dependence, pressure shift) that are specific to a given pair of species was added (K. Cady-Pereira, E. Mlawer, M. Alvarado). - A bug related to foreign broadening of oxygen transitions was fixed (E. Mlawer, M. Alvarado, K. Cady-Pereira). - A bug related to the use of the continuum in MonoRTM for near-IR cases was fixed (K. Cady-Pereira, M. Alvarado). * Spectroscopy - The default microwave line parameter files, spectral_lines.dat.0_55.v5.0_fast and spectral_lines.dat.0_55.v5.0_veryfast, now have a direct correspondence to the full AER linelist, whose current version is aer_v_3.3 (M. Alvarado, K. Cady-Pereira, E. Mlawer). - Numerous lines were added to the default microwave line files so that the calculational accuracy at any frequency between 0 and 899.4 GHz (0-30 cm-1) with respect to the full line list aer_v_3.3 is: # for spectral_lines.dat.0_55.v5.0_fast (corresponds to ISPD=0 in MonoRTM v4.2 and older): 0.1 K for upwelling, 0.2 K for downwelling # for spectral_lines.dat.0_55.v5.0_veryfast (corresponds to ISPD=1 in MonoRTM v4.2 and older): 0.5 K for upwelling, 1.0 K for downwelling (M. Alvarado, E. Mlawer, K. Cady-Pereira) NOTE: Users who wish to run MonoRTM v5.0 in spectral regions other than the MW should use the full AER line file (either aer_v_3.2 or aer_v_3.3), keeping in mind that the full line file can take a long time to run. - Line parameters were taken from HITRAN 2012 with the exceptions noted below. 1. 60 GHz O2 lines and 120 Ghz O2 line from Tretyakov et al. (2005), as implemented in MonoRTM v4.2. 2. 0 cm-1 "Debye line" for O2 same as in MonoRTM v4.2, all other O2 lines below 1.497951 cm-1 removed. 3. The intensities for the H2O lines at 0.7417 cm-1 (22.233 GHz), 6.1145 cm-1 (183.3 GHz), 10.84 cm-1 (325 GHz) and 12.68 cm-1 (380 GHz) are based on the work of S. A. Clough (1973) and are the same as in MonoRTM v4.2. 4. The foreign widths of the 22 and 183 GHz water vapor lines were rederived based on HITRAN 2012 line parameters using the approach of Payne et al. (2009). The temperature dependence parameters for these lines were adjusted from their HITRAN 2012 values to provide better agreement with calculations by Gamache (V. Payne, B. Gamache, E. Mlawer). - Broadening parameters were implemented for the following pairs of molecules: 1. Oxygen transitions broadened by water vapor based on Drouin et al. (2013) (E. Mlawer, K. Cady-Pereira) 2. Carbon dioxide transitions broadened by water vapor based on Sung (2009) (K. Cady-Pereira). 3. Water vapor transitions broadened by carbon dioxide based on calculations by R. Gamache of U. Mass. Lowell (K. Cady-Pereira). 4. Carbon dioxide transitions broadened by carbon dioxide based on calculations by R. Gamache of U. Mass. Lowell (K. Cady-Pereira). - The continuum was updated to MT_CKD_2.5. - Speed dependent parameters were implemented for CO2 transitions in the bands 68<-1 and 71<-1 (i.e., 30012<-00001 and 30013<-00001) following Devi et al. (2007a,b) (M. Alvarado). Karen Cady-Pereira, AER, December 2013 **************************************************************** Version 4.3 This version of MonoRTM includes the MT_CKD 2.5.2 continuum (updated from MT_CKD 2.4). This continuum update includes a bug fix to the N2 continuum. Note that versions 4.0 onwards of
