Interpretive Summary: The need for information on hydrological parameters over large areas requires new approaches. Remote Sensing is one such new approach. The capabilities of remote sensing techniques for observing hydrological parameters are described and documented in this paper.
Remote sensing provides a means of observing hydrological state variables over large areas. The ones which we will consider is this paper are: land surface temperature from thermal infrared data, surface soil moisture from passive microwave data, snow cover using both visible and microwave data, water quality using visible and near infrared data and estimating landscape esurface roughness using lidar. Methods for estimating the hydrometeorlogical fluxes, evapotranspiration and snowmelt runoff, using these state variables are also described.
