Particle size distributions from laboratory-scale biomass fires using fast response instruments
Particle size laboratory-scale biomass fires fast response instruments
2010/9/14
Particle size distribution from biomass combustion is an important parameter as it affects air quality, climate modelling and health effects. To date, particle size distributions reported from prior s...
A climatological perspective of deep convection penetrating the TTL during the Indian summer monsoon from the AVHRR and MODIS instruments
deep convection the TTL the Indian summer monsoon the AVHRR and MODIS instruments
2010/8/13
The impact of very deep convection on the water budget and thermal structure of the tropical tropopause layer is still not well quantified, not least because of limitations imposed by the available ob...
Sample drying to improve HCHO measurements by PTR-MS instruments: laboratory and field measurements
HCHO PTR-MS laboratory and field measurements
2010/2/21
A significant improvement in the PTR-MS instrument sensitivity to formaldehyde was obtained by drying the air sample to a dew point of −30 °C using a cold trap to condense and freeze water vapou...
Technical Note: Time-dependent limb-darkening calibration for solar occultation instruments
Time-dependent limb-darkening calibration solar occultation instruments
2010/1/18
Solar occultation has proven to be a reliable technique for the measurement of atmospheric constituents in the stratosphere. NASA's Stratospheric Aerosol and Gas Experiments (SAGE, SAGE II, and SAGE I...
Comparison of total ozone from the satellite instruments GOME and TOMS with measurements from the Dobson network 1996–2000
ozone GOME TOMS Dobson
2009/3/11
Over the last 3 decades, satellite data have been used to monitor long-term global changes in stratospheric ozone. The TOMS series (1978-present) and GOME (1995-present) are two very important instrum...
Intercomparison of O3 profiles observed by SCIAMACHY and ground based microwave instruments
Intercomparison O3 profiles microwave instruments
2009/2/16
Ozone profiles retrieved from limb scattering measurements of the SCIAMACHY instrument based on the satellite ENVISAT are compared to ground-based low altitude resolution remote sensors. All profiles ...
In-situ comparison of the NO>sub>y instruments flown in MOZAIC and SPURT
NO>sub>y instruments MOZAIC SPURT
2009/1/12
Two aircraft instruments for the measurement of total odd nitrogen (NOy) were compared side by side aboard a Learjet A35 in April 2003 during a campaign of the AFO2000 project SPURT (Spurengastranspor...
A study of polar ozone depletion based on sequential assimilation of satellite data from the ENVISAT/MIPAS and Odin/SMR instruments
polar ozone ENVISAT/MIPAS Odin/SMR
2008/12/1
The objective of this study is to demonstrate how polar ozone depletion can be mapped and quantified by assimilating ozone data from satellites into the wind driven transport model DIAMOND, (Dynamical...
Trend analysis of greenhouse gases over Europe measured by a network of ground-based remote FTIR instruments
greenhouse gases Europe FTIR instruments
2008/11/26
This paper describes the statistical analysis of annual trends in long term datasets of greenhouse gas measurements taken over ten or more years. The analysis technique employs a bootstrap resampling ...
First airborne water vapor lidar measurements in the tropical upper troposphere and mid-latitudes lower stratosphere: accuracy evaluation and intercomparisons with other instruments
airborne water vapor lidar troposphere mid-latitudes lower stratosphere intercomparisons
2008/11/19
In the tropics, deep convection is the major source of uncertainty in water vapor transport to the upper troposphere and into the stratosphere. Although accurate measurements in this region would be o...
