  2. Data AcquisitionFlow Chart

  3. Types of Data Sources Publically available data sources • Some are supported in LAPS • If unsupported, should they be added to repository? Locally available data • Each user sets up modified data ingest

  4. Data AcquisitionStrategies Convert your data to supported NetCDF / GRIB input formats supported by LAPS Ingest • Easy to port when installing new LAPS updates • Conversion is done prior to running LAPS Run a process independent of LAPS ingest that creates intermediate file (sched.pl may need modification) 3)Modify LAPS ingest software to handle your data • Not recommended unless data format is general enough for widespread use and software changes can be added to LAPS repository

  5. Data AcquisitionInformation • For each data type • Where to find publically available data • How to set up interface with unsupported or local data

  6. Wide Radar Volume Processing

  7. Recent Data AcquisitionImprovements Wideband Radar now processed from Volume Files Java Satellite Interface now available • Obtain data from NESDIS ADDE server MADIS Hydro and HADS data now supported Improved surface obs QC (e.g. stuck temperature/wind)

  8. Radar Volume Files Wideband Radar now processed from Volume Files • Augments existing options • Portable Java Interface • Processes Archive-II data (e.g. from UNIDATA) • Writes out one NetCDF file for each volume scan • Can be remapped from polar to Cartesian format with ‘remap_polar_netcdf.exe’ Description and Download available: • http://laps.noaa.gov/albers/remapper_raw.html Currently supports reflectivity and radial velocity Future support for Dual-Polarization parameters

  9. New Data Sources GPS Total Delay Radar • Dual-Polarization (e.g. for precip type) • Airborne Radar • Phased Array Radar (every minute) GOES-R Radiometers Pyranometers (Solar Radiation)
