Current Research Focus


The next generation TOR product that is currently being worked utilizes total column ozone from the Ozone Monitoring Instrument (OMI), which is on the AURA platform, and a stratospheric column ozone (SCO) amount from the Global Forecast System (GFS) model. The GFS model assimilates SBUV information and provides high resolution stratospheric profile information down to 100 hPa. Case studies for the summer of 2005 are currently being worked and will be added to the website shortly.

Air Quality Applications Work:

In FY 03, NASA's Earth Science Enterprise initiated a National Applications Program (NAP) comprising 12 applications, including air quality management. NAP bridges the gap between scientific discovery and practical applications to benefit society by providing Earth science data in forms readily usable by providers of essential services to the nation, bringing NASA data down to Earth.

Currently, there is a plan to compare tropospheric ozone derived from the next-generation TOR method (OMI-GFS TOR) with EPA ground station ozone data (over the U.S.) and forecasted ozone from the CMAQ model to determine the extent of the agreement between them. A prior case study (Fishman and Balok, 1999) had looked it but this work hopes to extend it both spatially and temporally.
