Summary

The design, performance and application of sensors for remote sensing of natural resources (vegetation, water, impervious surfaces, nutrients, and soil), water and energy fluxes, clouds, atmospheric pollutants, surface temperature and other land and aquatic resources is a very important front of remote sensing research to understands the physical, ecological, hydrological and environmental characteristics of surfaces and substances. The Special Issue of Remote Sensing Sensors will publish those full research and high rated manuscripts addressing the above issues and seek to understand the surface characteristics of land natural resources at various spatiotemporal scales. Sensor design to bridge the research gap of high spatial resolution with acceptable temporal scale, evaluation of performance of existing sensors and recommendations for improvement, identification of new windows of bands to discriminate noises from images, soil moisture sensors, wetland mapping, soil properties characterization, hydrological application, precipitation estimation and others applied to ecohydrological studies will be accepted.
 
Keywords

land surface characterization, land-cover, water and energy fluxes, soil moisture, albedo, emssivity, surface temperature, wetland delineation, latent heat flux, sensible heat flux, remote sensing of environment
