fromRTTOV

classmethod SRF.fromRTTOV(sat, instr, ch)

Read SRF from RTTOV format files.

Requires that in the TYPHONRC configuration file, the fields ‘srf_rttov’ in the section corresponding to instrument instr are defined to point to the respective files in RTTOV format. Within those definitions, {sat:s} will be substituted with the satellite name and {ch:>02d} with the channel number. For example, in typhonrc, we might have:

[hirs] srf_rttov = /path/to/rtcoef_{sat:s}_hirs-shifted_src_ch{ch:>02d}.txt

Parameters

• [str] (instr) – Satellite name, such as ‘noaa-15’

• [str] – Instrument name, such as ‘hirs’.

• [int] (ch) – Channel number (start counting at 1).
