First attempt of global-scale assimilation of subdaily scale soil moisture estimates from CYGNSS and SMAP into a land surface model

open access: yesEnvironmental Research Letters, 2021
Soil moisture performs a key function in the hydrologic process and understanding the global-scale water cycle. However, estimations of soil moisture taken from current sun-synchronous orbit satellites are limited in that they are neither spatially nor ...

Aplikasi Pengontrolan Kelembaban Tanah pada Smart Garden Menggunakan Sensor Soil Moisture

open access: yesJurnal Teknik, 2019
The problem of stabilizing soil moisture can be addressed by designing a soil moisture control application that serves to provide information on soil moisture conditions within a certain time period in the form of an order to water and stop watering. The

Spatially and Temporally Complete Satellite Soil Moisture Data Based on a Data Assimilation Method

open access: yesRemote Sensing, 2016
Multiple soil moisture products have been generated from data acquired by satellite. However, these satellite soil moisture products are not spatially or temporally complete, primarily due to track changes, radio-frequency interference, dense vegetation,

The effects of soil moisture, soil texture, and host orientation on the ability of Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae) to infect Galleria mellonella (Lepidoptera: Pyralidae) [PDF]

open access: yes, 2018
Entomopathogenic nematodes (EPN) demonstrate potential as a biological control for soil dwelling insects. However, edaphic factors, such as soil moisture and texture impact the efficacy of EPN on a host. The objectives were to examine the effects of soil

GLEAM v3: satellite-based land evaporation and root-zone soil moisture

open access: yes, 2016
. The Global Land Evaporation Amsterdam Model (GLEAM) is a set of algorithms dedicated to the estimation of terrestrial evaporation and root-zone soil moisture from satellite data. Ever since its development in 2011, the model has been regularly revised,

Multiscale soil moisture estimates using static and roving cosmic-ray soil moisture sensors [PDF]

open access: yesHydrology and Earth System Sciences, 2017
Soil moisture plays a critical role in land surface processes and as such there has been a recent increase in the number and resolution of satellite soil moisture observations and the development of land surface process models with ever increasing ...

Estimating soil moisture conditions for drought monitoring with random forests and a simple soil moisture accounting scheme [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2022
Soil moisture is a key variable for drought monitoring, but soil moisture measurements networks are very scarce. Land-surface models can provide a valuable alternative for simulating soil moisture dynamics, but only a few countries have such modelling ...
