2 nomads.ncdc.noaa.gov Being developed and integrated to provide one-stop access to widely distributed datasets, products, services Drought Portal geared toward providing critical information to decision-makers Climate Services Portal designed to reach a very wide segment of users – scientists, businesses, decision/policy-makers, news media, public, etc Model Portal provides access to reanalyses and numerical model output Many partners involved across NOAA, other agencies, and at the regional/state level

3 Desktop application providing simple visualization and data export of weather and climate data Supports 22 data formats (Model, Satellite and Radar) Based on community developed tools and standards Data interoperability with diverse user communities Export data to GIS, KMZ, NetCDF and text formats

4 Weather and Climate Toolkit export of 3D Radar sweeps and isosurfaces for Google Earth visualization

5 250 TBs of data now accessible online via NOMADS/National Climate Model Portal TBs per month of data downloaded Data volumes continue to grow as data are ingested from NCEP Access provided via OPeNDAP/HTTP/FTP/GridFTP Accommodate user’s most requested data by sub-setting long time series Foster research within geo-science communities (ocean, weather, and climate)

6 GIS Map Services provide centralized access to numerous datasets and products Web Services such as WMS, WFS, KML/KMZ (for Google Earth, etc) Access to the data and metadata, including machine to machine access Data visualization via tools such as Multigraph provide graphical display of various parameters Services continue to be built-out for additional datasets and products

7 Collection-level metadata (FGDC/ISSO) for many datasets not robust enough to allow for complex searches by parameter, time period, theme (eg, flooding, hurricanes), etc In some cases – no metadata record exist Finer-granule metadata (by location) often missing or lacking – eg, to allow for search by location (state, city, etc) of temperature data available for a specific date Wide range in data formats and in vocabularies used to describe the data Data integration very difficult due to these issues EDMC role? Emphasize the critical need for robust metadata, beginning at the dataset/product level

8 Growing number of user requests for larger volumes of data Major data campaigns – eg, NPP, JPSS, GOES-R, NEXRAD Dual Pol, CFSR, etc NOAA Climate Services Portal, Drought Portal, and National Climate Model Portal: increasing visibility and access for climatological data Advanced technology Web Services and GIS Services providing greater capabilities for users Direct machine to machine access for “power users” and for reprocessing efforts Higher resolution data (in-situ and gridded) – continuing to increase over time Data mining requirements (internal and external to NOAA) – eg, mining of NEXRAD data for precipitation and hail analyses Rapidly increasing internet bandwidth at lower costs, such as N-WAVE, and increasing CPU capabilities for users to manage large data volumes
