Terms of Reference

  • Develop remote sensing data for assimilation in cryospheric and hydrological models
  • Conduct assessment of errors in the retrieval of satellite cryospheric and hydrological parameters
  • Assemble historical records of consistently derived geophysical parameters for studies of changes and trends in the cryosphere and hydrosphere
  • Assess glacier and ice sheet mass loss and relationships to sea level rise with consideration of thermal expansion, tectonic causes and other factors.
  • Investigate the asymmetry in the changes of sea ice in the Arctic and Antarctic regions
  • Study trends and changes in albedo at high latitudes and relationships with changes in snow cover and melt patterns
  • Monitor variability and trends in surface temperature and how they affect snow cover, sea ice extent, glaciers and ice sheet volume, soil moisture and the permafrost regions
  • Measure, characterize, understand, and predict the storage and transport of momentum, heat, water (salinity), and greenhouse gases in the ocean and the surface signatures (temperature, salinity, dynamic topography) of the ocean’s response to surface forcing (wind stress, fresh water, turbulent and radiative heat flux) from diurnal to decadal time scales, and from coastal to open oceans
  • Understand the oceans’ role in the changes and interactions amongst the biological, chemical, and energy/water cycles in the oceans and their influence on terrestrial and cryospheric changes
  • Help coordinate present and future remote sensing missions especially those related to ocean, snow/ice, and terrestrial hydrological observations, and provide expertise in the calibration, validation, and dissemination of the resulting data
  • Develop early warning systems for natural disasters like droughts and floods


The International Society for Photogrammetry and Remote Sensing is a non-governmental organization devoted to the development of international cooperation for the advancement of photogrammetry and remote sensing and their applications. The Society operates without any discrimination on grounds of race, religion, nationality, or political philosophy.
