6-7 February 2012 BLLAST Workshop: Outcome of the 2011 BLLAST field experiment
8 February 2012 BLLATE 1&2 EUFAR meeting

Topics and objectives:

6-7 February - BLLAST workshop:

This will be the first meeting after the field experiment of the "Boundary Layer Late Afternoon and Sunset Turbulence" project, that took place in summer 2011.
The objective of the workshop is to summary and discuss what observations and data we have collected, show preliminary results, and organize our work on the data analysis and numerical simulation.

8 February - BLLATE 1&2 meeting:

The meeting aims at coordinating the quality control of the measurements taken from the aircraft platforms during BLLATE-1 and -2 EUFAR projects within the afternoon transition experiment BLLAST. Particular emphasis will be taken to discuss the data process and calibration factors, and to establish the analysis strategy of the inter-comparison flights. During the last part of the meeting, ongoing research based on the analysis of the aircraft observations and potential collaborations combining other data sets and modeling studies will discussed.


6-7 BLLASt workshop:

Monday 6 February, morning: Overview of the observations made.
Monday 6 February, afternoon: First analyses & preliminary results
Tuesday 7 February : Coordination of the work in data analysis and modelling, future events
