Interannual Variation of the Surface Temperature of Tropical Forests from Satellite Observations

open access: yesAdvances in Meteorology, 2016
Land surface temperatures (LSTs) within tropical forests contribute to climate variations. However, observational data are very limited in such regions. This study used passive microwave remote sensing data from the Special Sensor Microwave/Imager (SSM/I)

CLASSIFICATION OF ACTIVE MICROWAVE AND PASSIVE OPTICAL DATA BASED ON BAYESIAN THEORY AND MRF [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
A classifier based on Bayesian theory and Markov random field (MRF) is presented to classify the active microwave and passive optical remote sensing data, which have demonstrated their respective advantages in inversion of surface soil moisture content.

Reconstruction of Snow Depth Data at Moderate Spatial Resolution (1 km) from Remotely Sensed Snow Data and Multiple Optimized Environmental Factors: A Case Study over the Qinghai-Tibetan Plateau

open access: yesRemote Sensing, 2021
Snow depth distribution in the Qinghai-Tibetan plateau is important for atmospheric circulation and surface water resources. In-situ observations at meteorological stations and remote observation by passive microwave remote sensing technique are two main

An Effective Emission Depth Model for Passive Microwave Remote Sensing

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Knowing the exact penetration depth for passive microwave will enable us to gain a better understanding of the characteristics of the targets. But now, there is only a penetration depth model that can calculate the specific depth while it is suitable for active microwaves.

Estimation of Irrigation Water Use by Using Irrigation Signals from SMAP Soil Moisture Data

open access: yesAgriculture, 2023
Accurate irrigation water-use data are essential to agricultural water resources management and optimal allocation. The obscuration presented by ground cover in farmland and the subjectivity of irrigation-related decision-making processes mean that ...
