CEOS Instrument: New Infrared Sensor Technology




Instrument:NIRST
Agencies: CONAE [Primary]
 CSA
Mission: SAC-D/Aquarius
Status:Operational
Type:Multi-purpose imaging Vis/IR radiometer
Description:NIRST detects High Temperature Events (HTE), caused by biomass fires, volcanic eruptions, and other phenomena in order to measure their temperatures, and their released energy over land (fires & volcanic events). Supplementary measurements of land surface (LST) and sea surface temperatures (SST) off the coasts of South America and other targets of opportunity with 180 km swath, overlapping the Aquarius inner beams
Spatial Resolution: Space resol: 350 m (at nadir)
Swath Width: Instant: 182 km; Extended: 1000 km
Wavebands: Infrared push-broom scanner based on 2 linear uncooled microbolometric arrays sensitive to Mid-Wave Infra-Red (3.8 ?m) and Long-Wave Infra-Red (10.85 and 11.85 ?m) spectral bands respectively
Technology: Multi-purpose imaging Vis/IR radiometer
Description: Instrument designed to address more objectives by appropriate blending of the characteristics of spectral coverage and resolution, spatial resolution, radiometric accuracy, etc.. Spectral coverage in bands of Vis, NIR, SWIR, MWIR and TIR (0.4-15 Ám). Number of channels from a few to a few tens, separated by dichroics and filters. Channel bandwidths around 10 %. Spatial resolution typically 30m-3 km. Applicable in LEO and GEO.
