This special collection includes a series of papers that present the very first results from ESA's Earth Observation satellite mission, launched on November 22, 2013. This mission, which comprises three satellites at low Earth polar orbits, with two spacecraft flying side-by-side at low altitude (about 460km), and one flying at a slightly higher altitude (510km), provides high-precision and high-resolution measurements of the strength, direction and variation of the magnetic field, complemented by precise navigation, accelerometer and electric field measurements. These, and the constellation configuration, make it possible to separate and model the various sources of the geomagnetic field and investigate the in situ behavior of the ionosphere. This series of papers present the mission, some of its innovating instruments and the very first results and conclusions that could already be derived from the first year of Swarm in space.

Featured Special Collection

A Census of Atmospheric Variability from Seconds to Decades 

The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer.  This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census.  The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years.  The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades.  The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
