Data Description

JPSS CrIS IP (CrIS_IP)

In conjunction with the Advanced Technology Microwave Sounder (ATMS) the Cross-track Infrared Sounder collects atmospheric data to permit the calculation of temperature and moisture profiles at high (~ daily) temporal resolution. The Cross-track Infrared Sounder (CrIS) provides improved measurements of the temperature and moisture profiles in the atmosphere. Forecasters use temperature and moisture sounding data in advanced numerical weather prediction models to improve both global and regional predictions of weather patterns, storm tracks, and precipitation.

Notes

Beginning on August 11-14, 2014, CLASS started receiving the majority of JPSS data in gzip compressed format. The file names remained the same. Other than the file size being smaller, users do not need to make any changes to their software to use the data.

Spatial

Dataset Name / Granule ID / Beginning Orbit Number

Dataset Name Granule ID Beginning Orbit Number

Dataset name format is:

ProductID_(npp|j0[1234])_dyyyymmdd WHERE ProductID=any 5-character data product ID, yyyy=4-digit year, mm=2-digit month, dd=2-digit day or entire dataset name.

Example: RCRIS_npp_d20081010

Granule ID format is:

A 15 character string, where the first three characters are the satellite identifier of NPP. The next 12 characters are a zero left filled, 12 character number, specifying the number of tenths of a second since the first ascending node after launch. Allowable values are 1 through 999999999999.

Beginning Orbit Numberformat is:

An integer representing the number of the orbit at the start of the data collection for a data granule. The orbit number is incremented at each ascending node equatorial crossing.
