The Advanced Land Observing Satellite ALOS, developed by JAXA, follows the Japanese Earth Resources Satellite-1 (JERS-1) and the Advanced Earth Observing Satellite (ADEOS). The mission includes 2 optical and an L-band active microwave sensor payload whose data may be used for such applications as cartography, regional observation, disaster observation, and resources surveying. ESA will provide data for the European and African region.

Launched in March 1996 and ended in March 2004, IRS-P3 was an ISRO (Indian Space Research Organization) experimental EO mission, considered to be pre-operational and serving in parallel for technology evaluation and scientific methodology studies. IRS-P3 carried two remote sensing payloads: a Wide Field Sensor (WiFS) designed to study vegetation and a Modular Opto-electronic Scanner (MOS), dedicated to ocean and atmosphere monitoring.

JERS-1, launched in Feb 1992 and ended in Oct 1998, was a joint Japanese radar/optical mission with NASDA/JAXA lead. The overall objectives were the generation of global data sets with SAR and OPS sensors aimed at surveying resources, establishing an integrated Earth observation system, verifying instrument/system performances.
The mission applications focused on survey of geological phenomena, land usage, observation of coastal regions, geologic maps, environment and disaster monitoring and demonstration of two-pass SAR interferometry for change detection.

Kompsat-1 was a high resolution optical mission of Korea launched in 1999. Through a 3rd party mission agreement, ESA makes a sample dataset of European cities available from this satellite.
The Kompsat program was initiated in 1995 as a major space investment in Korea. Its objective was the development of a national space segment in Earth observation along with an efficient infrastructure and ground segment to provide valuable services to remote sensing users in various fields of applications.

Landsat TM/ETM

Landsat Thematic Mapper (TM) is a multispectral scanning radiometer that was carried on board Landsats 4 and 5. The TM sensors have provided nearly continuous coverage from July 1982 to present. The Landsat Enhanced Thematic Mapper (ETM) was introduced with Landsat 7. ETM data cover the visible, near-infrared, shortwave, and thermal infrared spectral bands of the electromagnetic spectrum.

Launched on 24 October 1978, the Nimbus-7 platform was the last mission belonging to the Nimbus Program, a meteorological research-and-development satellite program. This series of seven satellites, aimed primarily at testing new instruments and technologies, was operated by NASA and NOAA. The Nimbus-7 spacecraft was designed to sense and collect atmospheric and ocean colour data, and eventually the Nimbus series grew into an important Earth sciences program.
Among the instruments onboard the Nimbus-7 satellite was the Coastal Zone Colour Scanner (CZCS). This is a multi-channel scanning radiometer designed to map chlorophyll concentration in water, sediment distribution, temperature of coastal waters, ocean currents and gelbstoff concentration, as a salinity indicator.

QuikSCAT mission is a NASA/JPL mission to providing continuity to data from the NASA Scatterometer (NSCAT) mission. QSCAT data provide all-weather, high-resolution measurements of near-surface winds over global oceans to determine atmospheric forcing, ocean response, and air-sea interaction mechanisms on various spatial and temporal scales. QSCAT is used in operational weather forecasting as well as in scientific research, by combining wind data with measurements from scientific instruments in other disciplines to provide a better understanding the mechanisms of global climate change and weather patterns.

Launched in 1978, SeaSat was a NASA/JPL Earth Observation experimental mission, which had onboard the first ever spaceborne synthetic aperture radar (SAR) system for science applications. During its brief 106-day lifetime, SeaSat collected more information about the oceans than had been acquired in the previous 100 years of shipboard research.
