### Online Available LST Databases

Some operational LST products are freely available online. In most cases only an online registration form needs to be filled to have access to the products.

Some of the most well-known LST products available online are listed below.

### Land Surface Temperature from MODIS-Aqua & MODIS-Terra

LST products from MODIS satellites are available from 2002 onwards at several spatial and temporal resolutions (table II) from the Land Processes Distributed Active Archive Center (LP DAAC) managed by the NASA Earth Science Data and Information System (ESDIS) project. Fig. 30 presents an example of LST from MODIS on 21 June 2003.

### LST from the EUMETSAT Satellite Applications Facility on Land Surface Analysis

The EUMETSAT Satellite Applications Facility on Land Surface Analysis (LSA SAF) produces LST maps from SEVIRI sensor on board MSG each 15 minutes

Instrument: SEVIRI on board MSG satellites

Target accuracy: 2 K

Algorithm: Generalized split windows

Spatial coverage: MSG-Disk

Temporal frequency: 15 min.

Spatial resolution: 3 km subsatellite point

Projection: GEOS

Archive data: yes (since 2005)

File Format: HDF5

Data producers: EUMETSAT Satellite Application Facility (SAF) on Land Surface Analysis (LSA)

### Copernicus global maps of Land Surface Temperature from a constellation of geostationary satellites

Within the framework of the Global Land Service, the LST product was developed to increase the area coverage of the LST product currently distributed by LSA SAF. A near global product is obtained by merging SEVIRI (i.e., LSA SAF product) with GOES- and MTSAT-based LST.

Fig. 33: LST merged product from GOES, MSG and MTSAT satellites developed for the Copernicus Global Land Service.

Instrument: MSG, MTSAT, GOES

Target accuracy: 2 K

Algorithm: For MSG (SEVIRI) the LSA SAF Generalized Split Window algorithm is used. For MTSAT and GOES, a two-channel algorithm is applied to measurements from one MIR and one thermal window (TIR) channel during nighttime, and a mono-channel method requiring a single thermal window channel is used during the day.

Spatial coverage: MSG, GOES and MTSAT disks

Temporal frequency: 1 hour

Spatial resolution: 1 km

Projection: fixed grid map

File format: hdf5

Archive data: 2009-present

Data producers: IPMA-GIO

### LST from GEO and LEO instruments - ESA's GlobTemperature

GlobTemperature is an ESA project that provides access to multipurpose satellite-based land, lake and ice surface temperature data sets in a harmonized format through a single web portal.

Instruments: AATSR (Advanced Along Track Scanning Radiometer), ATSR2 (Along Track Scanning Radiometer 2), SEVIRI (Spinning Enhanced Visible and Infrared Imager), SSM/I (Special Sensor Microwave/Imager Radiometer).

Spatial coverage: Low orbit derived products have global coverage whereas LST from SEVRI is limited to the MSG disk area.

Projection: fixed grid map

File format: NetCDF-4 CF-Compliant "Harmonised Format"
