Swarm: ESA's Magnetic Field Mission

This brochure describes the satellite and the mission, and introduces the science.

Swarm Level 1b Processor Algorithms

The Swarm Level 1b Processor processes the Swarm Level 0 data from each of the three satellites individually and produces the Swarm Level 1b Data Products. This document contains the detailed description of the algorithms required for the processing.

Swarm Orbit Counter Specifications - ORBCNT

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.

CoReH2O - Report for Mission Selection - An Earth Explorer to observe snow and ice

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.
