Data Services

The Atmospheric Chemistry and Dynamics Branch makes available some kinds of data related to our research. Please note that these services are offered as a courtesy to fellow researchers; we are not equipped to become a general supplier of large quantities of data to the general public. There are other organizations to serve that role (NASA Goddard's own GSFC DAAC, for example, from which you can obtain actual meteorological analyses).

Therefore, feel free to browse and retrieve small samples of data. If you wish to transfer large quantities of data, please be considerate of our machine and network resources, and schedule your transfer between 8:00 PM and 5:00 AM Eastern Standard Time.

Available data:

TOMS Total Ozone data: These are daily global maps of total column ozone as measured by the TOMS instruments that have flown. (If you want to use these data for quantitative analysis, be sure to read the readme files that accompany them.)
Merged Total Ozone Data: Monthly mean total ozone data that have been merged together from six satellite instruments
Meteorological Plots: These are various plots of meteorological interest, most of which deal with the stratosphere. (Sorry, but there are no weather charts here.)
Southern Hemisphere ADditional OZonesondes (SHADOZ): Weekly balloon-borne ozonesonde data (ozone, pressure, temperature and RH parameters) from eleven tropical and sub-tropical stations since 1998.
The Goddard Automailer: Forms-based access to our e-mail autoresponder, which you can use to get plots and certain model runs.
Trajectory Analyses for the AERONET program: Kinetic trajectory analyses using the Schoeberl trajectory model applied by Anne Thompson's tropospheric group to DAO gridded fields in support of the AERONET (AErosol RObotic NETwork) program
Tropospheric ozone obtained from the "cloud-slicing" technique

For colleagues with whom we are in collaboration, we have other data services available.

Data Inventory

We are beginning to maintain lists of some of our data, to aid users in finding what they want.

Documentation:

df: A Proposed Data Format Standard (NASA Tech Memo 4467): This document describes the "df" format in which many of our data sets are written. Or you can get the whole Guide as a PostScript file. We also have a search page for this document.
