This brochure describes the satellite and the mission, and introduces the science.
This document is intended to describe the new Swarm Auxiliary data file containing the Swarm orbit numbers. The new Swarm Orbit Counter auxiliary data file is referred with a new dedicated product type (ORBxCNT), and it provides precise Swarm orbit number information to the scientific user community.
The objective of the CoReH2O mission is to fill the gaps in current information on snow, glaciers and surface water. CoReH2O will improve the modelling and prediction of water balance and stream-flow for snow-covered and glacierised basins, the modelling of water and energy cycles at high latitudes, and the forecasting of water supply from snow cover and glaciers, including the relation to climate change and variability.
The objective of the PREMIER mission is to quantify the processes controlling global atmospheric composition in the mid/upper troposphere and lower stratosphere (5-25 km height range), which is a region of particular importance for climate change.
The European Space Agency (ESA) launched the TIGER initiative in 2002, within the context of the Committee of Earth Observation Satellites (CEOS). The overall objective of the initiative is to assist African countries to overcome problems faced in the collection, analysis and use of water related geo-information by exploiting the advantages of Earth Observation (EO) technology.

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 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.
Definition of parameters to be used to generate inherent optical properties for the ocean and atmosphere as a function of geophysical properties and wavelengths, required for operating and testing of the MERIS ground segment processor. The current version is composed by 4 documents.
