Randal D Koster et al.
The assimilation of remotely sensed soil moisture information into a land surface model has been shown in past studies to contribute accuracy to the simulated hydrological variables. Remotely sensed data, however, can also be used to improv...

NASA's Soil Moisture Active Passive (SMAP) mission provides global surface soil moisture retrievals with a revisit time of 2-3 days and a latency of 24 hours. Here, to enhance the utility of the SMAP data, we present an approach for improvi...
The role of low-level terrain-induced jets in rainfall variability in Tigris-Euphrates Headwaters [0.03%]

Amin K Dezfuli et al.
Rainfall variability in the Tigris-Euphrates Headwaters is a result of interaction between topography and meteorological features at a range of spatial scales. Here, we have implemented the Weather Research and Forecasting (WRF) model, driv...
Verification of land-atmosphere coupling in forecast models, reanalyses and land surface models using flux site observations [0.03%]
基于通量观测试验的预报模式、再分析资料及地表模式陆气耦合检验研究

Paul A Dirmeyer et al.
We confront four model systems in three configurations (LSM, LSM+GCM, and reanalysis) with global flux tower observations to validate states, surface fluxes, and coupling indices between land and atmosphere. Models clearly under-represent t...
Benchmarking NLDAS-2 Soil Moisture and Evapotranspiration to Separate Uncertainty Contributions [0.03%]
NLDAS-2土壤湿度和蒸散发率的基准测试以区分不确定性来源

Grey S Nearing et al.
Model benchmarking allows us to separate uncertainty in model predictions caused by model inputs from uncertainty due to model structural error. We extend this method with a "large-sample" approach (using data from multiple field sites) to ...
Large Scale Influences on Summertime Extreme Precipitation in the Northeastern United States [0.03%]
影响美国东北部夏季极端降水的大尺度因素

Observations indicate that over the last few decades there has been a statistically significant increase in precipitation in the Northeastern United States and that this can be attributed to an increase in precipitation associated with extr...
Confronting weather and climate models with observational data from soil moisture networks over the United States [0.03%]
利用美国土壤水分观测网观测数据评估天气和气候模式中的土壤水分状况
Paul A Dirmeyer,Jiexia Wu,Holly E Norton et al.
Paul A Dirmeyer et al.
Four land surface models in uncoupled and coupled configurations are compared to observations of daily soil moisture from 19 networks in the conterminous United States to determine the viability of such comparisons and explore the character...
Utility of Satellite Remote Sensing for Land-Atmosphere Coupling and Drought Metrics [0.03%]
卫星遥感在土地-大气耦合和干旱指标中的应用价值

Feedbacks between the land and the atmosphere can play an important role in the water cycle and a number of studies have quantified Land-Atmosphere (L-A) interactions and feedbacks through observations and prediction models. Due to the comp...
The plumbing of land surface models: is poor performance a result of methodology or data quality? [0.03%]
陆面模型的数据同化:性能欠佳是由方法本身的问题还是数据质量问题导致的?
