In 1997, during the late stages of production NCEP–NCAR Global Reanalysis (GR), exploration a regional reanalysis project was suggested by GR project's Advisory Committee, “particularly if RDAS [Regional Data Assimilation System] is significantly better than global at capturing hydrological cycle, diurnal cycle and other important features weather climate variability.” Following 6-yr development effort, NCEP's North American Regional (NARR) completed in 2004, data are now available to...
Results are presented from the multi‐institution partnership to develop a real‐time and retrospective North American Land Data Assimilation System (NLDAS). NLDAS consists of (1) four land models executing in parallel uncoupled mode, (2) common hourly surface forcing, (3) streamflow routing: all using 1/8° grid over continental United States. The initiative is largely sponsored by Global Energy Water Cycle Experiment (GEWEX) Continental‐Scale International Project (GCIP). As overview for nine...

Intercomparisons cross‐validation tests conducted examine their performance various parts globe where station network densities different. gauge data in examinations quality controlled reports from roughly 16,000 stations that have...
A method of ocean color data processing using the combined near-infrared (NIR) and shortwave infrared (SWIR) bands for atmospheric correction Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua is proposed. MODIS-Aqua has been producing high quality products in open oceans, but there are still some significant errors derived coastal regions. With proposed NIR-SWIR algorithm, MODIS can be processed standard algorithm whereas turbid waters region SWIR executed. The water index...
Atmospheric correction for the ocean color products derived from Moderate Resolution Imaging Spectroradiometer (MODIS) uses two near‐infrared (NIR) bands centered at 748 and 869 nm. Ocean is usually assumed to be black these NIR wavelengths. For Case‐2 high productive Case‐1 waters, however, could have significant contributions in NIR, leading under‐estimation of MODIS‐derived water‐leaving radiances. This often case coastal regions. In this paper, measurements MODIS Terra short wave...

The leading component (PC) from summertime seasonal-mean data is associated with El Niño–Southern Oscillation (ENSO) while PC 30–60-day (Madden–Julian) oscillations (MJOs). monthly mean a hybrid two above-mentioned modes, capturing...
Atomic clocks based on laser-cooled atoms are widely used as primary frequency standards. Deploying such cold atom (CACs) in space is foreseen to have many applications. Here we present tests of a CAC operating space. In orbital microgravity, the cooled, trapped, launched, and finally detected after being interrogated by microwave field using Ramsey method. Perturbing influences from environment varying magnetic fields passage spacecraft through Earth's radiation belt also controlled...

Interannual variability of the summer monsoon in southwestern United States is controlled by various ocean- and land-based conditions (e.g., SST, soil moisture, snow cover) that provide sources memory antecedent climate anomalies such as ENSO. It hypothesized this interannual also modulated decade-scale fluctuations North Pacific SSTs. The following observations have been made support hypothesis. First, precipitation regime dominated a continental-scale pattern characterized an out-of-phase...
The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) and Moderate Resolution Imaging Spectroradiometer (MODIS) use the near-infrared (NIR) reflectance threshold at 865 nm (869 for MODIS) to discriminate clear sky from clouds processing of ocean color products. Such a simple scheme generally works well over open oceans where Case-1 waters maritime aerosols are usually case. However, in coastal regions, there often cases with significant contributions NIR wavelengths turbid waters. In addition,...

The region contains some of most consistently highly turbid waters be found anywhere. For waters, standard MODIS data processing often produces significant errors in ocean color products due contributions at two NIR bands. In this paper, we demonstrate an atmospheric correction...
