NOAA Global Data Service
The NOAA Global Data Service is based on the ATMS, CrIS and VIIRS data acquired, processed and formatted by the NOAA/NPOESS Data Exploitation (NDE).
03, November 2020
The GDS NOAA operational service consists of AVHRR and ATOVS global data which originates from the NOAA-19 spacecraft afternoon orbit.
The raw data Global Access Coverage (GAC) is dumped either at the NOAA ground stations in Fairbanks and Wallops Island in the USA or at the CDA located in Svalbard for 'blind orbit support'.
|Product Group||Timeliness||Data Access|
|AVHRR Level 1||2 hrs 15 mins||EUMETCast, Data Centre|
|AMSU-A Level 1||2 hrs 15 mins||EUMETCast, GTS/RMDCN, Data Centre|
|HIRS Level 1||2 hrs 15 mins||EUMETCast, GTS/RMDCN, Data Centre|
|MHS Level 1||2 hrs 15 mins||EUMETCast, GTS/RMDCN, Data Centre|
|ATOVS Sounding Products||3 hrs||EUMETCast, GTS/RMDCN, Data Centre|
Global SNPP/NOAA-20 data are provided as Sensor Data Records (SDR) (L1) and Environmental Data Record (EDRs) (L2).
The Advanced Technology Microwave Sounder (ATMS) is a new Microwave Sounder combining the capabilities of AMSU-A and MHS in a single instrument.
The Cross-track Infrared Sounder (CrIS) is an IASI-type Infrared Sounder optimised for meteorological sounding of the atmosphere. The CrIS SDRs are additionally tailored by decoding the BUFR data, retaining only a subset of channels for GTS dissemination.
A selection of Visible Infrared Imaging Radiometer Suite (VIIRS) level 2 products are made available.
Access to the data and products typically involves an initial registration process. For further information, please visit our Data Registration page, or register on the Earth Observation Portal (EOP).
Rapid Scanning Service
The Rapid Scanning Service scans the northern third of the Meteosat disc every five minutes.
Altimetry data is used to determine sea level height, wind speed and wave height.
Ocean colour services
Providing information on ocean living ecosystems, water quality and sediment dynamics.
