Decoding-Software-for-ERS-Data-for-FM94-BUFR.pdf

This document describes how to decode ERS Low Bit Rate (LBR) Fast Delivery (FD) products from the World Meteorological Organisation (WMO) standard FM94 BUFR format required for transmission to users via the WMO Global Telecommunications System (GTS).

Campaign

DOMEX-1

The purpose of the DOMEX experiment was to acquire the first combined, in-situ microwave emission measurements using C- and L-band radiometers.

Document - Technical Note

Draft-specification-of-ATSR-SADIST-2-products.pdf

This document is a draft specification of the scientific products from RAL's SADIST-2 ATSR data-processing software. Since SADIST-2 is being developed such that it can process data from both ATSR-1 and ATSR-2 instruments, the products described here have been designed to be sufficiently flexible and modular that they are equally valid for either instrument.

Activity - Projects

Dragon 2 Cooperation Programme

The Dragon 2 Programme focussed on the exploitation of ESA, ESA's Third Party Missions and Chinese Earth observation data for science and applications development in land, ocean and atmospheric applications.

Activity - Quality

EDAP

The ESA Earthnet Data Assessment Pilot (EDAP) project will perform assessments for various missions to ensure the delivered data is fit for purpose.

Mission - Heritage Missions

Envisat

Envisat was ESA's successor to ERS. Envisat carried ten instruments aboard for a wide range of Earth observing fields. The mission was operational from 2002 to 2012.

Document - Product Document

ENVISAT_AATSR_consolidated_Level-0_dataset_completeness.pdf

This document reports on the completeness of the AATSR consolidated Level 0 dataset. The analysis was performed by IDEAS and includes recommendations for building a clean and complete consolidated Level 0 dataset for reprocessing campaigns

Activity - General activities

EO Summer Schools

ESA's series of summer schools, on Monitoring of the Earth System, aims to promote the exploitation of Earth observation (EO) data.

Mission - Heritage Missions

ERS

The ERS programme was composed of two missions, ERS-1 and ERS-2, which together observed the Earth for 20 years, from 1991 to 2011.

ERS PRARE Precise Orbit Product (ERS.ORB.POD/ERS.ORB/PRC)

The precise orbit results from a data reduction process in which all available tracking data (Single-Lens Reflex, radar altimeter crossovers, PRARE range and Doppler data) and most accurate correction, transformation and dynamical models are taken into account and in which high level numerical procedures are applied. These orbits are "optimal" achievable representations of the real orbital motion under the circumstances of tracking situation and the "state of the art" model situation. The precise orbit product for the ERS satellites are the satellite ephemeris (position and velocity vector) including time tag, given in a well-defined reference frame, together with the nominal satellite attitude information and a radial orbit correction. Several orbit solutions are currently distributed: A new set of ORB POD (Precise Orbit Determination - REAPER v2) computed with the most updated model standards for the complete ERS-1 and ERS-2 mission. A previous set of ORB POD (REAPER v1) data already available on the ESA dissemination site since 2014, covering the ERS-1 full mission and the ERS-2 mission up to July 2003. ORB PRC which is the original Precise Orbit dataset computed during the ERS mission operations for ERS-1 and ERS-2. In the new POD dataset (REAPER v2) for the ERS-1 and ERS-2 missions, two different orbit solutions are provided together with the combined solution to be used for processing of the radar altimeter measurements and the determination of geodetic/geophysical products: those computed by DEOS (Delft Institute of Earth Observation and Space Systems), and those generated by ESOC (European Space Operations Centre) using different software (GEODYN and NAPEOS respectively). Careful evaluation of the various solutions of REAPER v2 has shown that the DEOS solution for both ERS-1 and ERS-2 has the best performance and is recommended to be used as reference. See the ERS Orbit Validation Report. For the previous version of the POD data set (REAPER v1), with ERS-2 mission data only up to 2003, three different orbit solutions together with the combined solution are available. These precise orbits for ERS-1 and ERS-2 have been computed at DEOS, ESOC, and GFZ (Deutschen GeoForschungsZentrums) using different software and different altimeter databases. Combined solutions have been created using three individual solutions for each satellite. All orbits were derived using consistent models in the same LPOD2005 terrestrial reference frame. These new orbit solutions show notable improvement with respect to DGME04 orbits (Scharroo and Visser, 1998). Thus, RMS crossover differences of new orbits improved by 4-9 mm. Careful evaluation of the various solutions has shown that the combined solution for both ERS-1 and ERS-2 has the best performance. All POD orbit files (REAPER v1/v2) are available in SP3c format.
