NHDS Access of Historical
Data
|
NHDS group provides access to historical data used for the calibration
of hydrologic models and development of hydrometeorologic techniques.
The inventory of historical data is a copy of other agencies data
that consists of:
- NCDC COOP and SAO stations
- NRCS SNOTEL sites
- USGS WATSTORE data
The historical data inventory is not up to date and are looking at
replacing it by accessing the data directly from the agencies. The
historical data that is available in it's raw format or OH
Datacard format. It is accessable on the web or by stand alone
programs. View the history of changes
to the NHDS Historical Raw Data Archive and software. (Note:
Please view the National
Weather Service Disclaimer regrading the information on this US
Government Server.)
There are several ways to access the historical data.
- Legacy fortran programs accessed through the web. These programs
were orginially written for mainframe and then ported to Linux
system with a web interface put on them. They access the data
stored in our inventory.
- Locate Station and Display Station Information from the archive of NCDC
and NRCS stations.
- Create OH Datacard time series
- Daily Data
- Hourly Precipitation Data
- This HP-UX binary executable utility, which is UNIX
compressed, will display a message if it detects a
problem with the datae sequence in the file. There
are two versions of the utility, one where the data
is in a 6 column format(
hlyver6.exe) or data in an 8 column format (hlyver8.exe).
To run the utility type the utility name followed
by the file name (example: hlyver6.exe datafile).
- Daily Potential Evapotranspiration
- NRCS SNOTEL sites
- USGS WATSTORE data
- Splits a datacard file that contains multiple stations
into multiple file that contain a single station. This
HP-UX binary executable utility, which is UNIX compressed,
(dsplit.exe)
splits the input file into mutliple file each containing
a single station. To run the utility type the utility
name followed by the file name (example: dsplit.exe
datafile).
- X/Motif version of the Historical Data Browser
- Web version of the Historical
Data Browser. This version will be a replacement of the X/Motif
version and the legacy fortran programs. The data access here
is from the agencies directly.
- A Utility (ts2oh) to convert PRDUTIL TSDATA reports to OH Datacard
format. The utility written for HP Unix environment and was written
for a special request, so use with caution. The latest release
was August 1, 2001. It is able to accept 1, 6, 12 and 24 time
steps and handle merging and cycling of large number of old datacard
