ESA's improved Earth system data records: what is in store for the future?
Fundamental Data Records (FDRs) are instrumental in advancing our understanding of Earth systems and for addressing societal challenges effectively. These long-term records contain uncertainty-quantified, calibrated and geo-located multi-instrument/multi-platform satellite sensor data spanning several decades to support climate-related applications.
Envisat MIPAS data now available on new ESA Dissemination Server
The latest reprocessed Envisat MIPAS Level 1 and Level 2 datasets have now been migrated from simple FTP access to the new Online Dissemination service for ESA Heritage Missions (HM) Atmospheric data.

Envisat MIPAS L2 - Temperature, pressure and atmospheric constituents profiles [MIPAS_2PS/2PE]
This MIPAS Level 2 data product describes localised vertical profiles of pressure, temperature and 21 target species (H2O, O3, HNO3, CH4, N2O, NO2, CFC-11, ClONO2, N2O5, CFC-12, COF2, CCL4, HCN, CFC-14, HCFC-22, C2H2, C2H6, COCl2, CH3Cl, OCS and HDO). It has a global coverage of Earth's stratosphere and mesosphere at all latitudes and longitudes. The vertical resolution of p, T and VMR profiles varies from 3 to 4 km, whereas the horizontal resolution is approximately 300 km to 500 km along track. This depends on the tangent height range and optical properties of the atmosphere. Auxiliary data include spectroscopic data, microwindows data, validation data, initial guess p, T and trace gas VMR profiles. The resolution range of the dataset is: 3 km (vertical) x 30 km (horizontal) at the tangent point. The latest reprocessed MIPAS Level 2 data (v8.22) is available as Standard products (MIPAS_2PS): A complete product containing 22 MIPAS L2 chemical species covering a single orbit and single species providing information generally needed by data users. Extended products (MIPAS_2PE): A complete product containing 22 MIPAS L2 chemical species covering a single orbit and single species intended for diagnostics and expert users who need complete information about the retrieval process. Both products are available in NetCDF format. Please refer to the MIPAS L2 v8.22 Product Quality Readme file for further details.
Envisat MIPAS L1 - Geo-located and calibrated atmospheric spectra [MIP_NL__1P]
This MIPAS Level 1 data product covers the geo-located, spectrally and radiometrically calibrated limb emission spectra in the 685-2410 cm-1 wave number range. It comprises 5 bands: 685-980 cm-1, 1010-1180 cm-1, 1205-1510 cm-1, 1560-1760 cm-1, 1810-2410 cm-1 and covers the following spatial ranges: Tangent height range: 5 to 170 km Pointing range: (azimuth pointing range relative to satellite velocity vector): 160° - 195° (rearward anti-flight direction); 80° - 110° (sideward anti-Sun direction). The instantaneous field of view (IFOV) is 0.05230 (elevation) x 0.5230 (azimuth)°. The length of measurement cell for an individual height step is approximately 300-500 km (dependent on tangent height and optical properties of the atmosphere). The spectral resolution spans from 0.030 to 0.035 cm-1, with a radiometric sensitivity of 4.2 to 50 nW / cm-1 / sr / cm2. The resolution range of the dataset is: 3 km (vertical) x 30 km (horizontal) at the tangent point. Please consult the Product Quality Readme file for MIPAS Level 1b IPF 8.03 before using the data.
