The LWIR camera acquired approximately 220,000 thermal-infrared images of the lunar surface that were used to generate the brightness temperature images within this archive. The procedure for generating brightness temperature values can be summarized as follows: 1) original LWIR digital numbers were converted to radiance; 2) the dark current signal was subtracted from the radiance values; 3) a flat field correction was applied; 4) bad pixels were identified and smoothed over; and 5) calibrated radiance values were converted to brightness temperatures using the Planck function.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.clem1-l-lwir-3-rdr-v1.0_krhz-mw2p", "issued": "2018-06-26", "keyword": ["deep-space-program-science-experiment", "moon", "sky"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=CLEM1-L-LWIR-3-RDR-V1.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "CLEMENTINE LWIR BRIGHTNESS TEMPERATURE V1.0"}
