CAWA (Advanced Clouds, Aerosols and WAter vapour products for Sentinel-3/OLCI) requirements baseline document provides information about the physical background, technical structure and the functional principle of the CAWA total column water vapour retrieval as defined within the CAWA project, which aims to the development and improvement of advanced atmospheric retrieval algorithms for the Envisat/MERIS and Sentinel-3/OLCI mission.
The purpose of this document is to help users identify the various types of data that are available from the ENVISAT, ERS-1 and ERS-2 Earth observing satellites, the kind of applications that the data may be used for and, importantly, the practical procedures required for access - including user registration and then search, selection and retrieval or ordering of the data of interest.
The purpose of this document is to define the guidelines to be followed for the formatting of the ENVISAT-1 Products, in order to get a consistent set of Payload Data Segment products, in terms of format, throughout the whole ENVISAT-1 mission.
The document is a brief guide for users to the ENVISAT 2nd generation Radar Altimeter (RA-2) and Microwave Radiometer (MWR) engineering (Level 1B) and geophysical (Level 2) Products Algorithms. Its immediate purpose is to convey basic information to users. The RA-2/MWR Product Handbook, which is now being drafted, will contain full details of the information needed by the users to exploit the RA-2/MWR data products.
