The following areas are identified as mutual interest areas for future cooperation between NOAA/ESRL/GSD and CWB:
  1. Develop and improve satellite products for tropical storm monitoring and prediction
  2. Realtime analysis and forecasting with ARPS system

  8. Continuing interaction on AWIPS related earlier cooperative projects

Develop and improve satellite products for tropical storm monitoring and prediction

NOAA/NESDIS (National Environmental Satellite, Data, and Information Service) will lead this task.  NESDIS will provide the access to advanced microwave satellite products, product analysis system and algorithms for SST and SSW products from the Aqua satellite.  NESDIS will also provide improved microwave sounding products and the data processing system from AMSU (Advanced Microwave Sounding Unit) and SSMIS (Special Sensor Microwave Imager and Sounder).

In order to demonstrate the forecast improvement value of using satellite data, NESDIS will improve the quality control software for microwave sounding products, develop tangent linear and adjoints of clouds and moisture physics, and demonstrate the use of microwave sounding products over land in the NWP system. 

Realtime analysis and forecasting with ARPS system

CAPS (Center for Analysis and Prediction of Storms) at the University of Oklahoma will set up an ARPS  (Advanced Regional Prediction System) domain within the CWB’s Nonhydrostatic Forecast System (NFS) model, assimilating  radar data for CWB’s initial ARPS Forecast System.   CAPS will perform case studies for heavy precipitation cases, that include the evaluation of domain size, computational requirements and configurations for HPC platforms, as well as forecast performance evaluation.   

Improvement and verification of short range forecasting using STMAS with remote sensing data

STMAS (Space and Time Multi-scale Analysis System) is a new and advanced data assimilation technique with a superior analysis advantage.  STMAS combines the advantages of objective analysis and modern variational analysis into a unified data assimilation system and removes the limitations of these data assimilation schemes.

Two STMAS tasks will be performed by GSD; one is STMAS surface analysis, and the other is STMAS 3D system implementation.  The surface analysis is mainly used for CWB weather reanalysis to provide the ground-truth for establishing climatology statistics.  The STMAS 3D system can further improve CWB weather reanalysis using upper air datasets to overcome the complex terrain effect.

HRQ2 (High-resolution Quantitative Precipitation Estimation and Quantitative Precipitation Forecast)

NOAA NSSL (National Severe Storms Laboratory) will continue research towards refinement, development, and maintenance of HRQ2 applications required for CWB, Water Resources Agency (WRA), and the Soil and Water Conservation Bureau (SWCB) operations.  The NSSL research is directed towards the integration of the dual-pol (dual-polarization) radar applications in the HRQ2 system.  This task will include the integration of the dual-pol radar reflectivity and the radar QPE in the real-time HRQ2 system to support CWB operations.  This task will perform an initial evaluation of the real-time reflectivity mosaic and QPE with dual-pol radar.

Enhancement of nowcasting decision and assistance tools

NOAA MDL (Meteorological Development Laboratory) will provide technical support to CWB to enhance CWB’s current forecast workstation, called the Weather Integration and Nowcasting System (WINS), in the area of nowcasting decision assistance tools.  One of the MDL missions is to develop a comprehensive suite of decision assistance tools, called SCAN (System for Convection Analysis and Nowcasting), implemented in AWIPS to cover the full scope of hydro-meteorological phenomena and forecaster responsibilities.  The current MDL activity is to migrate SCAN from AWIPS-1 to AWIPS-2.  MDL will also provide experience to CWB forecasters for training and evaluation of using other decisions assistance tools such as FFMPA (Flash Flood Monitoring and Prediction Advanced), and the preliminary Auto-NowCaster/AWIPS developed by NWS.

Development of high-resolution product generation assistance tools

ESRL/GSD will continue providing technical support on GFE, and Text Formatter (TF) and GHG (Graphical Hazards Generator) to support CWB’s development of formatter infrastructure of FIES (Forecast Information Editing System).  CWB plans to implement its own rule-based Chinese text formatter to provide a heavy rainfall report.  GSD will also provide necessary training to CWB visitor(s) to implement such a Chinese text formatter system as part of CWB’s FIES.   GSD will continue to coordinate necessary forecaster training of using BOIVerify (GFE/verification system) software training during hazardous weather situations. 

GPS Radio Occultation satellite data assimilation using the NCEP/JCSDA Gridpoint Statistical Interpolation (GSI) analysis system

As part of the COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate) mission,  CWB will support the inclusion of GPS Radio Occultation (RO) observations from the COSMIC mission into the NCEP’s regional system to implement the Gridpoint Statistical Interpolation (GSI) data assimilation of GPS radio occultation data under the joint collaboration project between NOAA/NASA/DoD, JCSDA and CWB.  NCEP is the National Centers for Environmental Prediction under NOAA’s NWS.  JCSDA (Joint Center for Satellite Data Assimilation) is a multi-agency research center tasked with improving the use of satellite data for analyzing and predicting weather, the ocean, climate and the environment.  JCSDA partner agencies are NASA (National Aeronautics and Space Administration), NOAA and DoD (Department of Defense). 

Continuing interaction on AWIPS related earlier cooperative projects

GSD will provide the latest AWIPS-1 releases and necessary test datasets to CWB.  GSD will continue to make available any latest AWIPS-build software, and technical support of AWIPS applications such as warning tools (WarnGen, GHG).  Under a NOAA/NWS contract to the Raytheon Technical Services Company (since 2005), a next generation of AWIPS (called AWIPS-2) is being developed.  GSD is tasked with performing an Independent Validation and Verification (IV &V) for each task order released by Raytheon.  GSD plans to share some of its experience with AWIPS-2 in the area of AWIPS-2 development environment.

Visiting Scients Program

Several areas of cooperation require CWB staff in residence at GSD. The primary effort of CWB staff at GSD during this period will be directed toward developing data assimilation techniques, the forecast workstation, and forecast preparation systems.
CWB visiting scientists program receives enormous support from GSD's different branches: Forecasting Application Branch, Information Systems Branch, Technology Outreach Branch and Information and Technology Service (ITS).  GSD also sent staff to CWB to provide training, technical support and scientific exchange.  Two project review meetings are scheduled for each year, one in Boulder during the early summer and one in Taiwan during the fall.
