| Zusammenfassung |
| We have quantified the relationship between Aerosol Index (AI) measurements
and plume height for young biomass burning plumes using coincident Ozone
Monitoring Instrument (OMI) and Cloud-Aerosol Lidar and Infrared Pathfinder
Satellite Observations (CALIPSO) measurements. This linear relationship
allows the determination of high-altitude plumes wherever AI data are
available, and it provides a data set for validating global fire plume
heights in chemistry transport models. We find that all plumes detected from
June 2006 to February 2009 with an AI value ≥9 are located at
altitudes higher than 5 km. Older high-altitude plumes have lower AI values
than young plumes at similar altitudes. We have examined available AI data
from the OMI and TOMS instruments (1978–2009) and find that large AI
plumes occur more frequently over North America than over Australia or
Russia/Northeast Asia. According to the derived relationship, during this
time interval, 181 plumes, in various stages of their evolution, reached
altitudes above 8 km. |
