Abstract Accurate snowfall measurements are necessary for meteorology, hydrology, and climate research. Typical uses include creating calibrating gridded precipitation products, the verification of model simulations, driving hydrologic models, input into aircraft deicing processes, estimating streamflow runoff in spring. These applications significantly impacted by errors solid measurements. Th...

To increase the number of direct observations rain and snow, we started a citizen science project that crowdsources precipitation phase reports from volunteers using smartphone app. We focused on Lake Tahoe region California Nevada, USA which forms part rain-snow transition zone, an area where both solid liquid occur in winter months. In two study years, received 2,495 reports, 2,248 (90.1%) pa...

We investigate the performance of one stretched-grid atmospheric global model, five different regional climate models and a statistical downscaling technique in simulating 3 months (January 1971, November 1986, July 1996) characterized by anomalous climate conditions in the southern La Plata Basin. Models were driven by reanalysis (ERA-40). The analysis has emphasized on the simulation of the p...

Coral reefs represent abrupt changes in surface roughness, temperature, and humidity oceanic coastal locations. This leads to formation of internal atmospheric boundary layers that grow vertically response turbulent mixing which conveys properties into the prevailing wind. As a result, coral under favourable conditions couple overlying atmosphere. Here we present rare observations reef – intera...

Accurate and consistent rainfall observations are vital for climatological studies in support of better planning and decision making. However, estimation of accurate spatial rainfall is limited by sparse rain gauge distributions. Satellite rainfall products can thus potentially play a role in spatial rainfall estimation but their skill and uncertainties need to be under-stood across spatialtime...
