Climatology Interdisciplinary Data Collection ------------------------------------------------------ I. Introduction ------------ This is the starting point to the Goddard DAAC Climatology Interdisciplinary Data Collection (CIDC), available on CD-ROM. The file index.html is an html version of this document which has links to all data and software documents. We recomend that you access the CD's through this file using your Web Browser. We have also supplied text (cd_booklet.txt) and Adobe Acrobat (cd_booklet.pdf) versions of the brochure that comes with the CD-ROM. ---------------------------------------------------------------------------- II. CIDC Data Set Groups -------------------- The CIDC consists mostly of monthly mean data from the atmospheric, oceanic, and land use sciences have been placed on a common global map grid, with standardized documentation. The Climatology Interdisciplinary Data Collection has been subdivided into seven categories based on data source as well as the parameters involved. * Atmospheric dynamics & atmospheric sounding products * Radiation and clouds * Biosphere data * Variable atmospheric constituents * Surface temperature and pressure * Hydrology data * Remote sensing science When practical, the data were put in a uniform spatial and temporal scale (1 degree x 1 degree, monthly). The OVERVIEW document contains a table of the data sets formats and characteristics and a second table lists alphabetically all the physical parameters in the CIDC collection. This dynamic data collection is being developed to meet the needs of interdisciplinary scientists, teachers and students for climate data concerning Global Change and seasonal and inter-annual variability. Climate scenarios on Global Warming, El Ni±o and the Indian Monsoon have been provided to give educators examples of topics in which the data can be used. The graphics used in these scenarios were created using the Grid Analysis and Display System (GrADS), which has also been put in this CD-ROM along with the necessary meta-data files required to read and display the data. We have also provided links to associated sites. ---------------------------------------------------------------------------- Climatology Interdisciplinary Data Available in this CD-ROM Collection Below is a listing of data available in this CD-ROM collection, subdivided into categories based on data source as well as the parameters involved.

CIDC Data at the Virtual Domain Application Data Center The Virtual Domain Application Data Center (VDADC), is located at George Mason University's, Institute for Computational Sciences and Informatics (CSI), Center for Earth Observing and Space Research (CEOSR). VDADC enables browsing and analysis of CIDC data over the WWW, before down loading the data over the Internet. A prototype of the VDADC, including an advance Java version, is accessible at the following URL: http://www.ceosr.gmu.edu/~vdadcp/ ---------------------------------------------------------------------------- IV.
