Research and Experiments at LACIS

an overview of LACIS-publications

set-up and measuring principle

some selected topics, introduced in more detail:

laboratory studies on particle hygroscopic growth and activation:

first measurements at high super-saturations
measurements at high relative humidities up to 99.1%
calibration of LACIS for super-saturations < 1%
measurements of atmospheric aerosol particles at sub- and super-saturation
deliquescence and efflorescence of succinic acid particles
a CCN-closure experiment for atmospheric HULIS particles
the LExNo - experiment (LACIS Experiment in November - a project founded by ACCENT):
determination of the accomodation coefficient of water
hygroscopic growth and activation of sea-salt particles and of sea-spray particles containing algal exudate (supported by EUROCHAMP)
towards closing the gap between hygroscopic growth and activation for SOA particles (supported by ACCENT and EUROCHAMP)
a sensitivity study examining the Köhler equation
a publication with an overview of results on the connection between hygroscopic growth and activation from years 2005 to 2008

field studies on particle hygroscopic growth and activation:

HACHI (HAze in CHIna): measurements of hygroscopic growth and activation in China

laboratory studies on immersion freezing:

FROST (FReezing Of duST): measurements and derived parameterizations of the immersion freezing of dust (supported by EUROCHAMP)
