DATEM - Data Archive of Tracer Experiments and MeteorologyProject OverviewThe availability of meteorological re-analysis archives, at several international centers, provides an opportunity to link high quality modern meteorological data with the data from many older long-range tracer experiments. Below is access to experimental data, relevant reports, meteorological data, statistical analysis, and display software, all in a common format for PC or UNIX applications. This data base permits the atmospheric transport modeling community to conduct various verification and sensitivity studies and compare model results with each other on a common basis. Currently, only longer range (10s to 1000s of km downwind) experimental data are considered, consistent with the spatial and temporal resolution of the meteorological re-analysis data. Users of the data base are encouraged to share any additional analysis software that they develop and prepare and submit additional experimental data to the archive. For more detailed information on the DATEM archive read the following paper available in Adobe PDF format. Data AccessThis pilot study incorporated data from five long-range dispersion experiments (described in more detail in the paper mentioned above), which represent a collection of more than 19,000 air concentration samples, re-analysis fields from the National Center for Atmospheric Research (NCAR) / National Centers for Environmental Prediction (NCEP) re-analysis project, and statistical analysis programs based upon the ATMES-II evaluation of ETEX. All the emissions and sampling data are in space delimited text files, easily used by Fortran programs or imported into any spreadsheet. Meteorological data fields have been reformatted for use by HYSPLIT and are available for download through the links provided below. The statistical programs are all written in Fortran and include PC executables with the source code so that they can be compiled on other platforms. Downloading Data
