نویسنده
چکیده
This paper presents a summary of a new laser-induced fluorescence instrument for airborne measurements of formaldehyde. As mentioned in the paper, accurate and precise measurements of formaldehyde are needed as they can provide an important constraint to test current models of atmospheric chemistry as well as provide retrieval validation for satellite measurements. The paper provides a detailed description of

A new airborne laser-induced fluorescence instrument for in situ detection of formaldehyde throughout the troposphere and lower stratosphere
The NASA In Situ Airborne Formaldehyde (ISAF) instrument is a high-performance laser-based detector for gas-phase formaldehyde (HCHO). ISAF uses rotational-state specific laser excitation at 353 nm for laserinduced fluorescence (LIF) detection of HCHO. A number of features make ISAF ideal for airborne deployment, including (1) a compact, low-maintenance fiber laser, (2) a single-pass design for...

متن کاملA new photolysis laser-induced fluorescence instrument for the detection of H2O and HDO in the lower stratosphere.
We present a new instrument, Hoxotope, for the in situ measurement of H(2)O and its heavy deuterium isotopologue (HDO) in the upper troposphere and lower stratosphere aboard the NASA WB-57. Sensitive measurements of deltaD are accomplished through the vacuum UV photolysis of water followed by laser-induced fluorescence detection of the resultant OH and OD photofragments. The photolysis laser-in...

متن کاملDevelopment and airborne operation of a compact water isotope ratio infrared spectrometer.
A sensitive laser spectrometer, named IRIS (water isotope ratio infrared spectrometer), was developed for the in situ detection of the isotopic composition of water vapour in the upper troposphere and the lower stratosphere. Isotope ratio measurements can be used to quantify troposphere-stratosphere exchange, and to study the water chemistry in the stratosphere. IRIS is based on the technique o...
