  1. Historical Data Access Basic Calibration Workshop March 10-13, 2009 LMRFC

  2. Historical Data Analysis MAPX 1. ‘Poor man’s” reanalysis

  3. Sources of Data for Calibration • National Climatic Data Center (NCDC) • Hourly precipitation (thru Feb, 2008 for legacy programs, 2005 for Browser) • Daily precipitation(through May, 2008 for legacy programs, 2005 for Browser) • Max, min temperature • Snow on Ground • Synoptic Data • Evaporation data. • U.S. Geological Survey (USGS) • Mean daily flow • Peak flow • Lake elevation • Pool elevation • Storage • Measurements (note: recently removed due to concerns) • Hourly Discharge (provisional) http://ida.water.usgs.gov/ida/

  4. Sources of Data for Calibration, cont’d • RFC Archives from NOAA Hydrologic Data System • NEXRAD • OFS Processed Data Base (PRD) • Point data and other Postgres data • RFC Archived Data Base • Natural Resources Conservation Service (NRCS) • Snotel data • IFLOWS (higher elevation data)

  5. Accessing Data for Calibration • Legacy programs on NHDS web site • Station Inventory • Daily Transfer • Hourly Transfer • Syntran (evaporation data) • Historical Data Browser (HDB) • GUI replacement of legacy programs

  6. Historical Data Access for Calibration Data Flow: Current System Meta Data (station inventory, history) on Postgres ‘OB9_Histdata’, to 1999, soon to be updated Meta Data (station inventory, history, on flat file, 2008) Web Access Legacy programs (stand alone) Data on NOAA1 Server (2008) Historical Data Browser (AWIPS) FTP OHD RFC

  7. Accessing Data for Calibration • In future we hope to have: • Updated Calibration System within CHPS • Incorporate • CAP • ICP • OPT3 • HDB • GIS • Access to NCDC and USGS directly

  8. Station History Information • No source is complete • New on-line resource: scanned versions of all NCDC B-44 forms reporting station information • Contact Cynthia.B.Karl@noaa.gov at NCDC • www.noaa.imcwv.com • metadata • cooperative station history forms • Document Coop Station Id Number ‘094648’

  9. RFC Data • A recent request for old NWSRFS data triggered an effort to retrieve all archived NWSRFS data for the period from 1996-Sept 2005. The data has been extracted from tape and placed on an OHD server. An inventory of NWSRFS files was then created on a RFC-by-RFC basis and can be found at: http://amazon.nws.noaa.gov/hdsb/data/nwsrfs/nwsrfs.html. • If you would like to request any old NWSRFS data, please email your request to nhdsinfo@gateway2.nws.noaa.gov.
