Reconstruction of a daily gridded snow water equivalent product for the land region above 45° N based on a ridge regression machine learning approach [PDF]

Earth System Science Data, 2022
The snow water equivalent (SWE) is an important parameter of surface hydrological and climate systems, and it has a profound impact on Arctic amplification and climate change. However, there are great differences among existing SWE products.

Testing homogeneity, stationarity and trend in climatic series at Udaipur – a case study

Journal of Agrometeorology, 2008
Three seasonal climatological time series, i.e., rainfall, minimum temperature, and maximum temperature of Udaipur in three seasons, i.e. summer, rainy and winter were tested for the presence of homogeneity, stationarity, and trend components.

Intercomparison of snow water equivalent products in the Sierra Nevada California using airborne snow observatory data and ground observations

Frontiers in Earth Science, 2023
Whereas many independent methods are used to estimate snow water equivalent (SWE) and its spatial distribution and seasonal variability, a need exists for a systematic characterization of inter-model differences at annual, seasonal, and regional scales ...

Multifidus Muscle Stiffness in Single-level Unilateral Lumbar Disc Herniation: Comparison of Two Shear-wave Elastography Methods

Haseki Tıp Bülteni, 2022
Aim:The suitability of shear-wave elastography (SWE) analysis in muscle tissue has been demonstrated previously. There are no studies that have applied the two SWE methods to evaluate the multifidus muscle in patients with lumbar disc herniation.
