Data - Data Description
Envisat ASAR AP Co- and Cross-polar L0 [ASA_APC/APH/APV_0P]
The ASAR Alternating Polarization Mode Level 0 (Co-polar and Cross-polar H and V) products contain time-ordered Annotated Instrument Source Packets (AISPs) corresponding to one of the three possible polarisation combinations: HH & HV, VV & VH and HH & VV, respectively. The echo samples in the AISPs have been compressed to 4 bits/sample using FBAQ. This is a high-rate, narrow swath mode, so data is only acquired for partial orbit segments. There are two co-registered images per acquisition and may be from one of seven different image swaths. The Level 0 product was produced systematically for all data acquired within this mode. Data Size: 56-100 km across track x 100 km along track. There are three AP Mode Level 0 products: ASA_APH_0P: The Cross-polar H Level 0 product corresponds to the polarisation combination HH/HV. ASA_APV_0P: The Cross-polar V Level 0 product corresponds to the polarisation combination VV/VH. ASA_APC_0P: The Co-polar Level 0 product corresponds to the polarisation combination HH/VV= H and H received/V transmit and V received.

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.
