RISThe Effect of Using Digital Satellite Imagery in the LAPS Moisture Analysis
Publisher: American Meteorological Society
Abstract: The Local Analysis and Prediction System (LAPS) analyzes three-dimensional moisture as one component of its system. This paper describes the positive impact that simple 8-bit, remapped, routinely available imagery have on ...
An Algorithm for Operational Water Vapor Analyses Integrating GOES and Dual-Channel Microwave Radiometer Data on the Local Scale
Publisher: American Meteorological Society
Abstract: An algorithm for the operational integration of satellite-derived and ground-based passive microwave precipitable-water measurements is presented. The technique merges the two data types by relying on the more. accurate ...
Applying Satellite Gradient Moisture Information to Local-Scale Water Vapor Analysis Using Variational Methods
Publisher: American Meteorological Society
Abstract: Horizontal shape matching (HSM) is a variational technique used to obtain an analysis that merges the gradient structure from one data source (e.g., satellite) with a background field. This technique is modeled after the ...
A Comparison of GOES Moisture-Derived Product and GPS-IPW Data during IHOP-2002
Publisher: American Meteorological Society
Abstract: Geostationary Operational Environmental Satellite (GOES) sounder?derived total column water vapor is compared with other data sources obtained during the 2002 International H2O Project (IHOP-2002) field experiment. ...
Multiscale Data Assimilation and Forecasting
Publisher: American Meteorological Society
NASA Cold Land Processes Experiment (CLPX 2002/03): Atmospheric Analyses Datasets
Publisher: American Meteorological Society
Abstract: This paper describes the Local Analysis and Prediction System (LAPS) and the 20-km horizontal grid version of the Rapid Update Cycle (RUC20) atmospheric analyses datasets, which are available as part of the Cold Land ...
Comparing Local Analysis and Prediction System (LAPS) Assimilations with Independent Observations
Publisher: American Meteorological Society
Abstract: Meteorological forcing data are necessary to drive many of the spatial models used to simulate atmospheric, biological, and hydrological processes. Unfortunately, many domains lack sufficient meteorological data and available ...
The Local Analysis and Prediction System (LAPS): Analyses of Clouds, Precipitation, and Temperature
Publisher: American Meteorological Society
Abstract: The Local Analysis and Prediction System combines numerous data sources into a set of analyses and forecasts on a 10-km grid with high temporal resolution. To arrive at an analysis of cloud cover, several input analyses ...
Real-Time Applications of the Variational Version of the Local Analysis and Prediction System (vLAPS)
Publisher: American Meteorological Society
Abstract: he accurate and timely depiction of the state of the atmosphere on multiple scales is critical to enhance forecaster situational awareness and to initialize very short-range numerical forecasts in support of nowcasting ...
An Evaluation of Five ARW-WRF Microphysics Schemes Using Synthetic GOES Imagery for an Atmospheric River Event Affecting the California Coast
Publisher: American Meteorological Society
Abstract: he main purpose of the present study is to assess the value of synthetic satellite imagery as a tool for model evaluation performance in addition to more traditional approaches. For this purpose, synthetic GOES-10 imagery ...
