RapidEye L3A time series dataset for Sentinel-2 available on-line

02 October 2013

In order to prepare for the exploitation of Sentinel-2 type of time series, the European Space Agency, in collaboration with RapidEye, collected an unprecedented time series from February to June 2013 with a 5 day revisit at high resolution over 14 selected sites around the world.

ACVE - Atmospheric Composition Validation and Evolution Workshop

13 - 15 March 2013

The European Space Agency is organising a workshop on Atmospheric Chemistry and Composition Validation and Product Evolution. The Workshop will be held from 13 to 15 March 2013 in ESRIN, Frascati, Italy.

The aim of the workshop is to present Cal/Val results from ENVISAT, ERS-2 and other Third Party Missions (GOSAT/Odin/OMI/SciSat/Terra-Aqua) to encourage contributions for future ESA missions (Earth Explorers, Sentinels) using existing data sets and Cal/Val infrastructures.

Modular Optoelectronic Scanner

The (MOS) is a spaceborne imaging spectrometer for the VIS/NIR-spectral range. It is designed for remote sensing investigations of the Atmosphere-Ocean-System, especially coastal zones

SWARM

19 December 2011

The primary aim of the Swarm mission is to provide the best survey ever of the geomagnetic field and the first global representation of its variations on time scales from an hour to several years.

It is clear that the nature of the Earth's magnetic field is complicated. It is also therefore clear that there is the need for a comprehensive separation and understanding of the external and internal processes that contribute to the Earth's magnetic fields – the Swarm mission aims to address such needs as well as allowing for new and exciting studies of the lithospheric field.

JERS Optical Sensor

JERS OPS is a high-resolution radiometer (a passive instrument) with the objective to measure sunlight reflected by the Earth's atmosphere in eight bands (color imagery). OPS consists actually of two independent radiometers: the VNIR band instrument and the SWIR radiometer. The Optical Sensor(OPS) provide better ground resolution than MOS-1's MESSR. The OPS separates the light reflected from the ground into seven spectral bands from visible to short-wave infrared and employes CCD's. Detailed pictures from the satellite allow us to survey the earth resources, monitor sea status and obtain other information useful for improving our life.

JERS Synthetic Aperture Radar

The JERS SAR is an active microwave sensor that transmits in microwave and detects the wave that is reflected back by objects. JERS SAR is completely different from passive optical sensors carried by the U.S. Landsat or Japan's Marine Observation Satellite-1/1b -1 (MOS-1/1b).

It enables high-resolution, high-contrast observation, and accurate determination, of topographical features, such as undulations and slopes, independently of weather conditions, even during fog or cloud cover.

EOC

The Electro-Optical Camera (EOC) is one of the instruments aboard the first Korea Multi-Purpose Satellite (KOMPSAT-1) (more info here). EOC is the primary payload for KOMPSAT-1. It has cartography mission to provide images for the production of scale maps, including digital elevation models, from a remote earth view in the KOMPSAT orbit. EOC collects panchromatic imagery with the ground sample distance (GSD) of 6.6 m and the swath width of 17 km at nadir through the visible spectral band of 510-730 nm. EOC scans the ground track of 800 km per orbit by push-broom and body pointing method.

MSC

The Multi-Spectral Camera (MSC) is a high spatial resolution imaging sensor which collects visible image data of the earth's sunlit surface. The MSC, the primary payload for the KOMPSAT-2, is a pushbroom-scanned sensor which incorporates a single nadir looking telescope. The sensor is submerged and rigidly attached to the spacecraft and the optical boresight of the telescope is aligned with the spacecraft +Z direction (nadir). The MSC collects PAN and MS monoscopic images of the earth. Stereoscopic images are made by ground processing of the images from multiple orbits. The MSC pointing is accomplished by rolling the spacecraft, as needed, so that the line of sight of the MSC may pass over the desired location or swath. At the nominal mission altitude with the spacecraft nadir pointing, the MSC collects data with a GSD of 1 meter for PAN and 4 meters for MS data and with a swath width of approximately 15 km. The MSC is designed to operate with a duty cycle of up to 20 % per orbit.

SLIM-6 imager

The SLIM-6 imager is a dual bank linear push broom imager utilising the orbital motion of the DMC platform to capture radiation reflected from the Earth's surface within a 600 km swath.

The spectral filter of each channel is protected by a fused silica radiation absorption window, which is positioned on the space facing side of the filter. The spectral filters are located in front of the camera lens. Each of the 6 SLIM-6 imager channels has a linear CCD array at its focal plane.
