| contents | <div> <p>The <strong>E</strong>ssential therma<strong>l</strong> <strong>I</strong>nfrared remo<strong>T</strong>e s<strong>E</strong>nsing (<strong>ELITE</strong>) product suite currently has four types of products, including land surface temperature (LST: clear-sky and all-sky), emissivity (NBE: narrowband emissivity; BBE: broadband emissivity; and spectral emissivity), the component of surface radiation and energy budget (SLUR: surface longwave upwelling radiation; SLDR: surface longwave downward radiation SLDR; SLNR: surface longwave net radiation), and the component of Earth’s radiation budget (OLR; outgoing longwave radiation; RSR: reflected solar radiation). The spatial-temporal resolutions of the ELITE products are mainly determined by the employed satellite data sources.

Each scene is stored as a GeoTIFF file named <code>FY3E_MERSI_LSTE_YYYYMMDD_hhmm.tif</code>, with 4 bands representing: LST, LSE@8.55μm, LSE@10.8μm, LSE@12.0μm.</p> <p> </p> <p>During validation, a small number of anomalously low values were identified, suggesting that some cloud-contaminated pixels were not effectively filtered by the FY-3E/MERSI CLM product.
