CEOS EO HANDBOOK – INSTRUMENT SUMMARY - NIRST -
Full Name New Infrared Sensor Technology Status Operational
Instrument Agencies CONAE, CSA Maturity
Instrument Type Imaging multi-spectral radiometers (vis/IR) Geometry Push-broom scanning
Instrument Technology Multi-purpose imaging Vis/IR radiometer Sampling Imaging
Data Access Constrained Access Data Format HDF-5/Geotif
Measurements and Applications NIRST (two linear microbolometric arrays, respectively sensitive to the TIR bands). It measures the characteristics of high temperature events on land (fires & volcanoes) and sea surface temperatures on selected targets.
