Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Charles Darwin (74AB) cruise CD62A
Short name CD62A
Objectives and Narrative ERS-1 calibration and validation in the region of the Iceland-Faroes Front.
The overall aim of the cruise was to calibrate and validate data from the sensors on board the European Space Agency ERS-1 satellite against in-situ measurements, to improve the utility of that data for oceanographic studies.
Specific objectives included:
1. the validation of ERS-1 altimeter significant wave height measurements.
2. The calibration and validation of ERS-1 altimeter wind speed measurements.
3. the validation of ERS-1 altimeter sea surface topography measurements.
4. The calibration and validation of ERS-1 scatterometer wind speed and direction measurements.
5. The investigation of the relationship between wind stress at the sea surface and radar backscatter as measured by the scatterometer (including the effect of wave conditions on this relationship).
6. The calibration and validation of ERS-1 Along Track Scanning Radiometer (ATSR) sea surface temperature (SST) measurements.
