The NASA Goddard Kinematic Trajectory Model (KTM) [Schoeberl and Sparling, 1995] is used to forecast the transport of the volcanic plume through 21 April. Parcels are initialize in the model on a 1.0 deg. latitude by 2.5 deg. longitude grid every 0.25 deg. in latitude and every 0.50 deg. in longitude centered on the location of the Eyjafjallajokull volcano (63.63 deg. N, 19.60 deg. W). Parcels are injected every 500 m from 1.5 km to 10.0 km at 18:00 and 24:00 UTC on 14 April, then every 500 m from 1.5 km to 2.5 km every two hours from 2:00 to 18:00 UTC on 15 April to simulate the observed continuous injection of air parcels. The KTM is run using meteorological data from the National Centers for Environmental Prediction, with analysis data to the present time, then in forecast mode to future times (resolution of 1 deg. latitude by 1 deg. longitude by 6 hours). The associated animation shows the possible evolution of the plume over time, with the heights of the plume indicated by the color coding. The animation can be found as a PDF or QuickTime Movie.
This PDF and QuickTime Movie show the entire Northern Hemisphere.
NEW: This PDF and QuickTime Movie are based on satellite observations made on 15 April 2010. Parcels were initialized on a 6.0 deg. latitude by 20 deg. longitude grid centered on 61.0 N, 2.0 W every 0.5 km in the vertical from 1.5 to 10.0 km, every 1.5 hours from 7.5 to 19.5 UTC on 15 April 2010. This grid of parcels was run backwards for 2 days. Those parcels coming within 25 km of the volcano site were noted, with all altitudes allowed before 2359 UTC on 14 April 2010 and only altitudes < 2.5 km allowed after that time. These parcels were then used to initialize a 7-day forward run of the KTM, shown in the animations linked above. NOTE that this simulation assumes no additional plume input after 1930 UTC on 15 April 2010.
With funding from the Japan-U.S. Educational Commission through the Fulbright Program and from NASA's Earth Science Division, we will be investigating the impact of pollution from China on air quality in Japan. With the occurance of the Olympic games in Beijing during August 2008 and the pollution control measures that China is implementing to meet air quality requirements, this summer presents an unprecidented opportunity to examine the impact of China's pollution on regional and global pollution budgets. Using Aura satellite data, balloon and surface data from Japan, trajectory models, we will be investigating these questions in 2008 and 2009. From July - Septmeber each year, we will work at Hokkaido University with colleagues in the School of Environmental Science taking data. Then from October - November each year, we will work with scientists in Japan at the Frontier Research Center for Global Change analyzing the data. Thanks to Fulbright, NASA, and our hosts in Japan at Hokkaido University and FRCGC. Follow along on the Olympics data link.

If you find a balloon payload, do not be afraid. They contain nothing dangerous, although the battery may be smelly. Just store it in a dry, outdoor location until you can return it. We'd like to know where and when you found it. Just email us. Also, if you mail the payload back to NOAA in Boulder, CO, you can earn a $30 reward..
