AIRS ozone comparison with simulated ozone precursor transport, morphed ozone + emissions dispersion:7/92: The ozone monitoring data from the AIRS database is compared to the simulated transport of ozone precursors, using CAPITA the Monte Carlo Model (July 18 - 25, 1992) with two hour time steps. The ozone transport simulation is the same movie as Ozone transport simulation using the CAPITA Monte Carlo model .; RecID: Webmaster22

Ozone precursor transport simulation using the CAPITA Monte Carlo model: This is a simulation of the transport of ozone precursors over the Eastern US. It is similar to the flow visualization movie: Flow visualization with the CAPITA Monte Carlo model; however, the particles have been colored based on the cummulative weighted sum of the particle's VOC and NOX mass, i.e., "ozone" mass = VOC+6*NOX.; RecID: Webmaster21

Flow visualization with the CAPITA Monte Carlo model: The animation shows a dynamic flow simulation of airmasses over North America during 7/1/1992 - 7/14/1992. The left hand side of the movie contains the spatial location of all particles emitted at a constant rate from a spatially uniform grid at the surface layer of the atmosphere. The particles have been colored based upon their height.; RecID: Webmaster20

Hourly NE Ozone and Back Trajectories from 8/23-28, 1992: This is a comparison of measured ozone in the Northeast (left), with back-trajectories (right) during August 23-28, 1992. The bottom left time chart shows the ozone pattern at Albany, NY (solid line) and at Adams in northwestern Massachusetts. The model is the same as in The monitoring data were extracted from the AIRS database, and the back trajectories were created using the CAPITA Monte Carlo; RecID: Webmaster19

Hourly NE Ozone and Back Trajectories on 6/13/92: This is a comparison of measured ozone in the Northeast (right), with back-trajectories (left) during June 13-15, 1992. The monitoring data were extracted from the AIRS database, and the back trajectories were created using the CAPITA Monte Carlo.; RecID: Webmaster18

Hourly NE Ozone and Back Trajectories on 5/23/92: This is a comparison of measured ozone in the Northeast (right), with back-trajectories (left) during 5/23/92. The monitoring data were extracted from the AIRS database, and the back trajectories were created using the CAPITA Monte Carlo.; RecID: Webmaster17

Forward Trajectories over the Eastern US during the summers of 1991-1995: Forward trajectories from 20 receptor sites evenly distributed over the Eastern US. The trajectories extend for three days after their release from each source during the three months June - August for the years 1991 - 1995.; RecID: Webmaster3

Back Trajectories over the Eastern US during the summers of 1991-1995: Back trajectories from 20 receptor sites evenly distributed over the Eastern US.

Hourly US AIRS data of O3, NO, NO2, NOX, SO2, CO, NMHC for ten years (1986-1995): Each file contains one month of hourly data. For each year six months of data are extracted (April-September). The data are in Voyager, ASCII formats. The ASCII files also contain the original AIRS workfile for each month.; RecID: Webmaster
