Description
STRATEOLE 2 is a French-American project based on long-duration measurements under superpressure balloon to study dynamics and processes in the TTL and the lower stratosphere. Here we present water vapor measurements by the Pico-SDLA diode laser spectrometer during the first campaign (Dec. 2019 - Feb. 2020).
In this presentation, we analyse the regional in situ tape recorder signal obtained. We discuss the challenges beyond such analysis. The anomaly of the in situ measurements with respect to a satellite-borne mean climatology from Aura MLS v5 allows the identification of singular events responsible for modulation of the local water vapor content : Kelvin wave, packet of gravity waves and possibly deep convection.
