SRF Data Download Notes

This page contains NetCDF format datafiles of SRFs for a number of broadband satellite infrared sensors. Generally, apart from some Meteosat channels, SRFs in these files do not go beyond 3200cm-1 (<3.125µm). Also, where applicable, the SRFs are band averaged. In the case of the MODIS instruments, both the band averaged and individual detector SRFs are provided.

The point of this page is to collect in one place, and in one format, the SRFs of many of the instruments in use today. For most instruments, the data were reformatted into a common ASCII format by Hal Woolf of CIMSS/SSEC/UW-Madison at a frequency spacing of 0.1cm-1. I simply added some additional information to the ASCII files and then converted them to netCDF format.

The original SRF data have been linearly (re)interpolated where required:
     Broadband SRFs: 0.1cm-1 frequency spacing (e.g. 800.0, 800.1, 800.2, etc.)
     AIRS SRFs: 0.0025cm-1 frequency spacing (e.g. 800.0, 800.0025, 800.005, etc.) from the UMBC HDF data.

The SSU SRFs are completely synthetic with an 8th power Gaussian used (for lack of any other information). The SSU SRFs for TIROS-N and NOAA-6 are based on the same central frequencies, and those for NOAA-7,8,9,11, and 14 are based on a slightly different set of central frequencies.

If you need to download multiple files rather than one or two from the tables below, it behooves you to go directly to the anonymous ftp server.

1The label NOAA-5 is used to refer to the TIROS-N satellite instruments here rather than
the operational NOAA-5 (ITOS-H) satellite. The primary sensors for the ITOS-H satellite
were the Very High Resolution Radiometer (VHRR), Vertical Temperature Profile Radiometer
(VTPR), and Scanning Radiometer (SR).
