SATELLITE OBSERVATIONS OF TROPOSPHERIC COMPOSITION: A NEW ERA OF RESEARCH

BIG PROBLEMS IN TROPOSPHERIC CHEMISTRY

HOW TO ADDRESS THESE PROBLEMS?

OBSERVATION SYSTEM FOR TROPOSPHERIC COMPOSITION very sparse at present; satellites will change this

MOST OBSERVATIONS OF ATMOSPHERIC COMPOSITION FROM SPACE HAVE BEEN FOR THE STRATOSPHERE

TROPOSPHERIC COMPOSITION FROM SPACE: platforms, instruments, species

OCCULTATION MEASUREMENTS (UV to near-IR)

SOLAR BACKSCATTER MEASUREMENTS (UV to near-IR)

THERMAL EMISSION MEASUREMENTS (IR, wave)

LIDAR MEASUREMENTS (UV to near-IR)

THE GOME SATELLITE INSTRUMENT

GLOBAL BUDGET OF TROPOSPHERIC OZONE

RELATING TROPOSPHERIC NO2 AND HCHO COLUMNS TO NOxAND VOC EMISSIONS

OPTIMIZATION OF NOX EMISSIONS USING GOME

HIGHER SPATIAL RESOLUTION FROM SCIAMACHY

HCHO COLUMNS MEASURED BY GOME (JULY 1996)

GOME HCHO COLUMNS OVER NORTH AMERICA (JULY 1996)

ISOPRENE EMISSION INVENTORIES, JULY1996

OZARKS “ISOPRENE VOLCANO” AS SEEN BY GOME

SEASONALITY OF GOME HCHO COLUMNS (9/96-8/97) Largely reflects seasonality of isoprene emissions; notable differences with GEIA

EMISSION CONTROL STRATEGY FOR OZONE POLLUTION: ARE NOx OR VOCs THE LIMITING PRECURSORS?

NADIR OBSERVATION OF CARBON MONOXIDE BY IR EMISSION

THE NASA/TRACE-P AIRCRAFT MISSION (Mar—Apr 2001)

INTEGRATION OF TRACE-P, MOPITT, AND GEOS-CHEM TO QUANTIFY CARBON MONOXIDE SOURCES FROM ASIA

EOS AURA SATELLITE (2004 launch)
