BackForwardInstrument:  HSI (GLIMR) 

Instrument details
Acronym HSI (GLIMR)
Full name Geosynchronous Littoral Imaging and Monitoring Radiometer Hyperspectral Imager
Purpose To provide observations of ocean biology, chemistry, and ecology for rapidly evolving phytoplankton dynamics and hazards such as Harmful Algal Blooms (HABs) and oil spills.
Short description
  • A hyperspectral imager covering spectral range 350-1020 nm at 5 nm sampling.
  • There is a seperate imager (LMI) to identify landmarks for geolocation.
Background

New development
Scanning Technique

The imager has a telescope on a two-axis gimbal to actively scan the HSI and LMI through N-S and E-W motions
Resolution 300 m over America at low latitudes
Coverage / Cycle Area observed 20.8° N-S and E-W
Mass Power Data Rate
