Melt water runoff from seasonal snow in the High Atlas range is an essential resource Morocco. However, there are only few meteorological stations high elevation areas and therefore it challenging to estimate distribution of equivalent (SWE) based on situ measurements. In this work we assessed performance ERA5 MERRA-2 climate reanalysis compute spatial SWE Atlas. We forced a distributed snowpac...

Atmospheric reanalyses are widely used for understanding the past and present climate. They have become increasingly within renewable energy sector assessing wind solar resources different regions of globe in conjunction with observations. Mexico is a country considerable potential production, especially around coastal sites therefore characterization resource these areas imperative most benefi...

In this article we analyze 11 years of near-surface meteorology using observations from an open-ocean surface mooring located in the Northwestern Tropical Atlantic (51°W, 15°N). Air-sea fluxes heat, freshwater, and momentum are derived these Coupled Ocean–Atmosphere Response Experiment (COARE) bulk parameterization. Using dataset, compute a climatology annual cycle meteorological conditions air...

Diurnal S[Formula: see text] tidal oscillations in the coupled atmosphere-ocean system induce small perturbations of Earth's prograde annual nutation, but matching geophysical model estimates of this Sun-synchronous rotation signal with the observed effect in geodetic Very Long Baseline Interferometry (VLBI) data has thus far been elusive. The present study assesses the problem from a geophysic...

Precipitation-gauge observations and atmospheric reanalysis are combined to develop an analoguemethod for detecting heavy precipitation events based on prevailing large-scale atmospheric conditions. Combinations of atmospheric variables for circulation (geopotential height and wind vector) and moisture (surface specific humidity, column and up to 500-hPa precipitable water) are examined to cons...

The chemical composition dataset of Aerosol Reanalysis NASA’s Modern-Era Retrospective Analysis for Research and Application, version 2 (MERRAero) has not been thoroughly evaluated with observation data in mainland China due to the lack long-term components data. Using 5-year PM10 mass concentrations compositions obtained from routine sampling measurements at World Meteorological Organization G...

The northwest Greenland Ice Sheet (NW GrIS) is rapidly losing mass, and its ablation zone has expanded over the past two decades. Numerous supraglacial streams flowing directly NW GrIS surface drain a large lobe of grounded ice at Inglefield Land, into proglacial Minturn River Nares Strait. Owing to absence moulins crevasses, this continuous supraglacial-proglacial drainage system regulates eva...

Abstract There has been a statement that the satellite and reanalyses significantly overestimate snow depths (SDs) as compared with in-situ observations over Tibetan Plateau (TP). The inconsistency may be partly due to representations related different spatial resolutions. To further clarify matters of scale, this work estimates compares fractional cover (FSC) from MODIS (500 m), SDs Sentinel-1...
