Evaluation of SMAP Freeze/Thaw Retrieval Accuracy at Core Validation Sites in the Contiguous United States [PDF]
Remote Sensing, 2018 Seasonal freeze-thaw (FT) impacts much of the northern hemisphere and is an important control on its water, energy, and carbon cycle. Although FT in natural environments extends south of 45°N, FT studies using the L-band have so far been restricted ...

Proceedings of the 9th ACM/IEEE International Conference on Information Processing in Sensor Networks, 2010 We present the architecture, specification, and implementations of a simple monitoring and action profile (sMAP), optimized for sensors, meters, and actuators in building environments. Our architecture is built on HTTP/REST and uses JSON as the object format for interoperability.
