Abstract

This document represents and Algorithm Theoretical Basis Document (ATBD) for developing an Earth System Data Record (ESDR) quantifying global vegetated land surface freeze/thaw state (F/T) dynamics. The freeze/thaw ESDR (FT_ESDR) will be developed using multi-frequency satellite passive and active microwave remote sensing time series spanning multiple missions and sensors, including passive microwave radiometery from the Scanning Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave Imager (SSM/I) and Advanced Microwave Scanning Radiometer for EOS (AMSR-E), and radar scatterometry from SeaWinds-on-QuikSCAT. These records are global in extent and provide a contiguous time series extending from 1979 onward with some overlap between missions.
