Comparison between LPMA measurements 3D Reprobus modelling using a box model : sensitivity of vertical profiles to time, latitude, longitude and implications on NOy modelling
Mixing ratio profiles of ozone and several NO_y species were measured using the Limb Profile Monitor of the Atmosphere (LPMA) instrument during ascent, occultation and sunset for a balloon flight, which took place on August 21, 2001 from Kiruna (Sweden). These profiles were compared with the Reprobu...
