The RFP requests that three NOAA data sites be evaluated for integration with the Flood DSS:
• Meteorological Assimilation Data Ingest System (MADIS)
• National Digital Forecast Database (NDFD)
• FX-Collaborate (FXC)
The NOAA MADIS is a data flow system that ingests, integrates, quality controls, and
distributes hydrometeorological observations from NOAA and non-NOAA sources (http://www-
sdd.fsl.noaa.gov/MADIS Overview/MADIS Overview.html). Some of the datasets are
restricted for redistribution, while others are public. MADIS currently contains several datasets
that may be relevant to the Flood DSS, including hydrometeorological data from the National
Weather Service, Colorado Department of Transportation, and the Denver Urban Drainage and
Flood Control District, among other sources. MADIS is a flexible system that can collect data
from new sources based on user interest. Real-time data are updated every five minutes.
Historical data have been archived back to 2001. The data may be obtained in several ways,
including ftp, using free data management software, or through aText/XML Viewer web service.
During the data inventory, Riverside will evaluate in conjunction with the State of Colorado
whether the benefit from integrating these datasets warrants the system development costs.
Of the three NOAA data sites mentioned in the RFP, NDFD is likely to be the most easily
integrated into the Flood DSS. It includes a number of operational climate and outlook data
elements that are relevant to the Flood DSS (see Table 4-4). During the data inventory process,
Riverside will evaluate integrating gridded datasets from the NDFD, which are provided in
GRIB2 format. The data are updated hourly to an ftp and an http download site. For integration
with the Flood DSS, a process would need to be developed to download the data for the Central
Rockies region and process the data into a usable format for the State of Colorado. The data are
