Impacts of Satellite-Based Snow Albedo Assimilation on Offline and Coupled Land Surface Model Simulations
Seasonal snow cover in the Northern Hemisphere is the largest component of the terrestrial cryosphere and plays a major role in the climate system through strong positive feedbacks related to albedo. The snow-albedo feedback is invoked as an important cause for the polar amplification of ongoing and projected climate change, and its parameterization across models is an important source of uncer...
متن کاملAssimilation of MODIS Snow Cover Fraction Observations into the NASA Catchment Land Surface Model
The NASA Catchment land surface model (CLSM) is the land model component used for the Modern-Era Retrospective Analysis for Research and Applications (MERRA). Here, the CLSM versions of MERRA and MERRA-Land are evaluated using snow cover fraction (SCF) observations from the Moderate Resolution Imaging Spectroradiometer (MODIS). Moreover, a computationally-efficient empirical scheme is designed ...
متن کاملScanning multichannel microwave radiometer snow water equivalent assimilation
[1] Accurate prediction of snowpack status is important for a range of environmental applications, yet model estimates are typically poor and in situ measurement coverage is inadequate. Moreover, remote sensing estimates are spatially and temporally limited due to complicating effects, including distance to open water, presence of wet snow, and presence of thick snow. However, through assimilat...
متن کاملBias correction of satellite soil moisture and assimilation into the NASA Catchment land surface model
Surface soil moisture data from different sources (satellite retrievals, ground measurements, and land model integrations of observed meteorological forcing data) have been shown to contain consistent and useful information in their seasonal cycle and anomaly signals even though they typically exhibit very different mean values and variability. At the global scale, in particular, it is currentl...
متن کاملA methodology for snow data assimilation in a land surface model
[1] Snow cover has a large influence on heat fluxes between the land and atmosphere because of its high albedo and insulating thermal properties. Hence accurate snow representation in coupled land-ocean-atmosphere global climate models has the potential to greatly increase prediction accuracy. To this end, a one-dimensional extended Kalman filter analysis scheme has been developed to assimilate...
