Abstract

The Global Ozone Monitoring Experiment (GOME) was an instrument aboard ERS-2. The main scientific objective of the GOME mission is to measure the global distribution of ozone and several trace gases which play an important role in the ozone chemistry of the Earth's stratosphere and troposphere, for example, NO2, BrO, OClO, and SO2.

This dataset contains version 1.1 ozone profiles derived by the Remote Sensing Group (RSG) at the STFC Rutherford Appleton Laboratory, Oxfordshire, UK, as part of the National Centre for Earth Observation (NCEO). These were derived from radiances measured by the GOME on-board ERS-2. The collection also includes total column ozone, column BrO, and column NO2 as well as cloud heights derived from the Along Track Scanning Radiometer (ATSR), which are included to aid interpretation of the ozone profiles.

Mobile platform operations

Mobile Platform Operation 1 Mobile Platform Operation for: European Remote Sensing satellite 2 (ERS-2)

Computation Element: 1

Title Deployed on European Remote Sensing satellite 2 (ERS-2)
Abstract This computation involved: deployed on European Remote Sensing satellite 2 (ERS-2). European Remote Sensing satellite Two (ERS-2), successor and nearly identical to ERS-1. It follows the same orbit as ERS-1 and was launched in April 1995. ERS-2 was nearly identical to ERS-1. The platform is based on the design developed for the French SPOT satellite. Payload electronics accommodated in a box-shaped housing on the platform; antennas fitted to a bearing structure. ERS-2 carries the following instruments: AMI - active microwave instrument consisting of a synthetic aperture radar (SAR) and a wind scatterometer (both in the C-band). RA- radar altimeter: takes precise measurements of the distance from the ocean surface and of wave heights. ATSR - along-track scanning radiometer (operating in the infra-red and visible ranges): measures sea surface temperatures and the vegetation cover of land surfaces. GOME - global ozone monitoring experiment, an absorption spectrometer which measures the presence of ozone, trace gases and aerosols in the stratosphere and troposphere. MS - microwave sounder: supplies data on atmospheric humidity. PRARE - precise range and range rate equipment: ERS orbit and trajectory determination. LRR - laser reflector: determines satellite position using ground-based laser stations. IDHT - instrument data handling and transmission: temporary on-board data storage by means of two 6.5 GBit tape recorders, equivalent to the data volume acquired in one orbit. Recording, formatting and transmission of data at 105 Mbit/s (transmission of SAR imaging data in real time), or 15 Mbit/s (transfer from tape recorder).
