    "title": "NOAA Climate Data Record (CDR) of Daily Outgoing Longwave Radiation (OLR), Version 2.0",
    "description": "This Climate Data Record (CDR) contains the daily mean Outgoing Longwave Radiation (OLR) time series in global 1 degree x 1 degree equal-angle gridded maps spanning from January 1, 1979 to present, and continuing daily with a two-day lag. The OLR is estimated from radiance observations from the operational polar-orbiting sounding instruments, including HIRS, IASI and CrIS, via multispectral OLR algorithm for HIRS, and spectral flux estimation algorithms for the hyper-spectral instruments, along with other temporal and spatial averaging methodologies. These OLR CDR products are generated with HIRS\/IASI\/CrIS OLR retrievals from TIROS-N series satellites, MetOp series satellites, and JPSS series satellites. The OLR retrievals are inter-satellite calibrated and maintain radiometric traceability, while using geostationary-estimated OLR to accurately account for diurnal variations for Daily mean product derivation. The new HIRS OLR regression coefficients improve the retrieval consistency between HIRS-based OLR retrievals and IASI\/CrIS-based OLR retrievals. The data file format is netCDF-4 with CF metadata, and it is accompanied by algorithm documentation, data flow diagram and source code for the NOAA CDR Program.",
