Strategies for using remotely sensed data in hydrologic models [PDF]

Present and planned remote sensing capabilities were evaluated. The usefulness of six remote sensing capabilities (soil moisture, land cover, impervious area, areal extent of snow cover, areal extent of frozen ground, and water equivalent of the snow ...

Effective UV surface albedo of seasonally snow-covered lands [PDF]

, 2007
International audienceAt ultraviolet wavelengths the albedo of most natural surfaces is small with the striking exception of snow and ice. Therefore, snow cover is a major challenge for various applications based on radiative transfer modelling.

What Do Latest CMIP6 Global Climate Models Say About Future Arctic Sea Ice Coverage Changes?

International Journal of Climatology, EarlyView.
Modelling of sea ice dynamics has significantly improved between CMIP5 and CMIP6, with nearly three times as many models capturing realistic annual variability in sea ice extent (SIE). What we previously thought was a non‐linear pattern of low SIE observations in 2007–2010 that would continue throughout time now appears to be non‐record‐setting lows in

Heatwave Characteristics and Trends Across Eight Japanese Cities

International Journal of Climatology, EarlyView.
Heatwaves occur with high likelihood across Japan. Strong north–south contrasts exist in heatwave characteristics. Southern locations experience more frequent, longer, and more intense heatwaves. Since 1955 there has been an increase in heatwave frequency, duration, and cumulative heat, particularly for nocturnal heatwaves. ABSTRACT This study provides

Research relative to angular distribution of snow reflectance/snow cover characterization and microwave emission [PDF]

Remote sensing has been applied in recent years to monitoring snow cover properties for applications in hydrologic and energy balance modeling. In addition, snow cover has been recently shown to exert a considerable local influence on weather variables ...

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

International Journal of Climatology, EarlyView.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, EarlyView.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

Validation of the SNOWPACK model and reconstruction of multidecade snow climatology at Ram Mountain (Alberta, Canada) forced with NARR data

Arctic, Antarctic, and Alpine Research
In remote Canada, sparse meteorological stations hinder reliable snow data collection, especially for assessing historical records. Yet, these data are crucial to evaluate the effect of climate change on ecosystems and species.

Operational applications of satellite snowcover observations in Rio Grande drainage of Colorado [PDF]

Various mapping techniques were tried and evaluated. There were many problems encountered such as distinquishing clouds from snow and snow under trees. A partial solution to some of the problems involves ground reconnaissance and low air flights.

Extreme Climate Events in Morocco: Historical Analysis and Future Projections Based on CMIP6 Simulations

International Journal of Climatology, EarlyView.
Historical observations and bias‐corrected CMIP6 projections reveal intensifying warm extremes, declining cold events and increasingly irregular precipitation patterns across Morocco. Future warming, particularly under SSP5‐8.5, produces an almost linear amplification of heat, aridity and hydrological stress, leading to longer droughts and more intense
