The service provides the latest reprocessed Envisat MIPAS Level 1 data (IPF v8.03).

See MIPAS products availability table.

The data is collection based and allows data browsing and download via treeview, filename or advanced catalogue search.

Data download is available via HTTPS, including bulk download functionality. ESA internal users can use their ESAAD account to access the HTTPS Dissemination Service.

Access to ftps://hm-atmos-ds.eo.esa.int is available via common FTP clients using implicit FTP over TLS and your own EO Sign In credentials. For internal ESA users the ESAAD account cannot be used for FTP access.

New users can register an account on EO Sign In. For further information about the EO Sign In Service you can visit TellUs.

Should you need support to access the data, please contact EOHelp.

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.
