ABSTRACT
INTEX-NA
is a two phase experiment that aims to understand the transport and transformation
of gases and aerosols on transcontinental/intercontinental scales and
assess their impact on air quality and climate. The primary constituents
of interest are ozone and precursors, aerosols and precursors, and the
long-lived greenhouse gases. The first phase (INTEX-A)
was completed in the summer of 2004 and the second phase (INTEX-B) is
to be performed in the spring of 2006. This document is intended to provide
an update on the goals of INTEX-B and define its implementation strategy.
The scientific goals envisioned here are based on the joint implementation
of INTEX-B, MIRAGE-Mex and DLR/IMPACT studies and their coordination with satellite observations.
In collaboration with these partners, the main goals of INTEX-B are to:
- Quantify the transpacific transport and evolution
of Asian pollution to North America and assess its implications
for regional air quality and climate;
- Quantify the outflow and evolution of gases and aerosols from the
Mexico City Megaplex;
- Investigate the transport of Asian and North America pollution
to the eastern Atlantic and assess its implications for European
air quality;
- Validate and refine satellite observations of tropospheric composition;
- Map emissions of trace gases and aerosols and relate atmospheric
composition to sources and sinks
The INTEX-B field study is to be performed during
an approximate 8-week period from March 1 to April 30, 2006... >> View
