—Ground surface freeze–thaw cycles caused by changes in solar radiation have a great impact on soil–air water heat exchanges due to the phase transition of pore water. This influence should not be ignored in the land surface process and global environment change studies because of its large extent and the rapid changes in daily and seasonal frozen ground.(More)
Numerical and experimental investigations of broadband random vibrational energy harvesting using monostable and bistable piezoelectric cantilevers are presented along with relative performance comparisons. Simulations and experiments reveal that a linear-monostable energy harvester can outperform its bistable counterpart for very low and relatively high(More)
The Complicate Observations and Multi-Parameter Land Information Constructions on Allied Telemetry Experiment (COMPLICATE) comprises a network of remote sensing experiments designed to enhance the dynamic analysis and modeling of remotely sensed information for complex land surfaces. Two types of experimental campaigns were established under the framework(More)
Frozen soil is best observed by microwave remote sensing due to the big difference of the permittivity comparing with unfrozen soil. The dielectric property of frozen soil has much relation with its microwave radiation. So permittivity is a bridge parameter in monitoring the status of frozen soil and its water content using microwave remote sensing.(More)
