Coefficients Download
Coefficient files for many non-hyperspectral sensors are included with the source code distribution. All coefficient files are available on this page which provides a comprehensive list of the latest RTTOV coefficient files along with the features supported by each one. Use these tables to determine the best coefficient file(s) to use for your instrument(s) of interest.
See this page for RTTOV v12 coefficients.
Atlas Download
Surface Emissivity Atlas Data
The IR emissivity atlas angular correction and covariance files are optional and can be downloaded separately from the emissivity data itself.
The following files should be unzipped/untarred in emis_data/:
- UW IR emissivity atlas files (unchanged since v11.3)
- UW IR atlas data – this includes the angular correction data
- UW IR atlas covariance data – optional
- UW IR atlas angular correction data – optional
- CAMEL 2007 IR emissivity atlas files (unchanged since v12)
- CAMEL atlas data – this includes the UW IR atlas angular correction data
- Optional, the CAMEL climatology IR atlas standard deviation data (links below) can be used with the CAMEL 2007 atlas in RTTOV v13, or for RTTOV v12 use the UW IR atlas covariance data above
- UW IR atlas angular correction data – optional, the UW IR atlas angular correction data can be used with the CAMEL 2007 atlas
- CAMEL climatology IR emissivity atlas files (unchanged since v12.3)
- CAMEL climatology atlas PC data – required
- CAMEL climatology atlas data: January-March, April-June, July-September, October-December
- CAMEL climatology atlas standard deviation data: January-June, July-December – optional
- UW IR atlas angular correction data – optional, the UW IR atlas angular correction data can be used with the CAMEL climatology atlas
- TELSEM2 MW atlas and interpolator (unchanged since v12)
- TELSEM2 MW atlas – this includes a Fortran module which allows TELSEM2 to be used independently of RTTOV.
NB These are ASCII files and as such it is not necessary to compile RTTOV with the HDF5 library to use TELSEM2.
- TELSEM2 MW atlas – this includes a Fortran module which allows TELSEM2 to be used independently of RTTOV.
- CNRM MW atlas (unchanged since v12)
Surface BRDF Atlas Data
The following file should be unzipped/untarred in brdf_data/:
- BRDF atlas files (unchanged since v11.3)
