Radio Frequency Interference Detection in Passive Microwave Remote Sensing Using One-Class Support Vector Machines

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Radio frequency interference (RFI) is a serious threat to the accurate estimation of critical geophysical parameters via passive microwave remote sensing and the presence of RFI in microwave radiometer measurements is increasing over time.

Assessment of the total precipitable water from a sun photometer, microwave radiometer and radiosondes at a continental site in southeastern Europe [PDF]

open access: yesAtmospheric Measurement Techniques, 2019
In this study, we discuss the differences in the total precipitable water (TPW), retrieved from a Cimel sun photometer operating at a continental site in southeast Europe, between version 3 (V3) and version 2 (V2) of the AErosol RObotic NETwork (AERONET)

Simulating the Influence of Temperature on Microwave Transmissivity of Trees During Winter Observed by Spaceborne Microwave Radiometery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Forest transmissivity is a key parameter for understanding spaceborne and airborne observations of the Earth's land surface because not only does it influences the proportion of subcanopy upwelling microwave emission penetrating through the forest canopy,

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.
