Bias Characteristics of COSMIC RO Data within Clouds Based on Different Background Fields
The Global Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation (RO) from 2007 to 2009 were collocated with the CloudSat nadir-pointing cloud profiling radar (CPR) in time and space in this study.We ...

Prediction of Sunspot Cycles by Data Assimilation Method [PDF]
Despite the known general properties of the solar cycles, a reliable forecast of the 11-year sunspot number variations is still a problem. The difficulties are caused by the apparent chaotic behavior of the sunspot numbers from cycle to cycle and by the ...

Seasonal forecasting of subsurface marine heatwaves
Marine heatwaves damage marine ecosystems and services, with effects identified mostly below the ocean surface. To create a truly user-relevant detection system, it is necessary to provide subsurface forecasts.

Assimilating SAR-derived water level data into a hydraulic model: a case study [PDF]
Satellite-based active microwave sensors not only provide synoptic overviews of flooded areas, but also offer an effective way to estimate spatially distributed river water levels.

Intra-hour cloud index forecasting with data assimilation [PDF]
We introduce a computational framework to forecast cloud index (CI)fields for up to one hour on a spatial domain that covers a city. Such intra-hour CI forecasts are important to produce solar power forecasts of utility scale solar power and distributed ...

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.
