LSTM-based data integration to improve snow water equivalent prediction and diagnose error sources

Journal of Hydrometeorology, 2023
Accurate prediction of snow water equivalent (SWE) can be valuable for water resource managers. Recently, deep learning methods such as long short-term memory (LSTM) have exhibited high accuracy in simulating hydrologic variables and can integrate ...

Global Sensitivity Analysis of the MEMLS Model for Retrieving Snow Water Equivalent

IEEE Transactions on Geoscience and Remote Sensing, 2022
Sensitivity analysis (SA) of model parameters is of great importance for understanding, development, and application of models. However, the influence of snow microstructure variability on snow water equivalent retrieval from passive microwave ...

Retrieval of Snow Water Equivalent, Liquid Water Content, and Snow Height of Dry and Wet Snow by Combining GPS Signal Attenuation and Time Delay

open access: yesWater Resources Research, 2019
For numerous hydrological applications, information on snow water equivalent (SWE) and snow liquid water content (LWC) are fundamental. In situ data are much needed for the validation of model and remote sensing products; however, they are often scarce ...

Retrieval of Snow Water Equivalent by Gamma

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Snow cover can attenuate gamma rays in soil, take advantage of this property, the surface snow water equivalent over a large range can be measured more accurately, and it has the advantage of not destroying the surface characteristics. Considering the disturbance of soil moisture to the measurement results and the geographical characteristics of the ...

InSAR for estimation of changes in snow water equivalent of dry snow

IGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2001
This paper describes the theoretical relation between interferometric phase and changes in snow water equivalent (SWE) and show results from experiments using ERS- 1/2 tandem data. The main scattering contribution from a dry snow cover is from the snow-ground interface. However, the radar wave will be refracted in the snow.

Snow Depth and Snow Water Equivalent Estimation

2021
Variation in regional and global snowfall significantly affects the ecological and climate systems, which is usually used for policy-making in water resource management and disaster prevention. The amount of snowfall is measured by two different parameters, snow depth and snow water equivalent (SWE). SWE is defined as the product of snow depth and snow
