The Toolsets for Airborne Data (TAD), developed at the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center (LaRC) to promote the airborne data use, is now available. This beta-release is an intuitive user interface for variable selection across different airborne field studies and includes features to create merge files based on a user’s choice of time base. In addition, the TAD merge feature allows users to generate standard deviation and to process point-by-point uncertainties and limit of detection values. Prior to accessing the TAD Web Application ( for the first time, users must create a free URS account and/or authorize TAD to use their account. Each page of the web application offers access to a quick YouTube video walkthrough, documentation that explains more about the TAD motivation and use, links to partners that made this effort possible, and more information, including available flight dates and flight tracks for each mission and the platform(s) for which data is currently offered.


Currently TAD has eight data sets: DISCOVER-AQ MD, ARCTAS (DC-8), INTEX-B, INTEX-NA, NEAQS (NOAA), TeXAQS 2006 (NOAA), ARCPAC (NOAA), and CalNex (NOAA), and the output files are in the ICARTT format. The data sets from DISCOVER-AQ California, Houston and Colorado, DC3, and SEAC4RS will be added shortly. We are currently focused on the in situ measurements and we want to hear from you about the need for other data sets in your research.
