Zusammenfassung |
In the framework of ACTRIS (Aerosols, Clouds, and Trace Gases Research
Infrastructure Network) summer 2012 measurement campaign (8 June–17 July
2012), EARLINET organized and performed a controlled exercise of feasibility
to demonstrate its potential to perform operational, coordinated
measurements and deliver products in near-real time. Eleven lidar stations
participated in the exercise which started on 9 July 2012 at 06:00 UT and ended
72 h later on 12 July at 06:00 UT. For the first time, the single calculus
chain (SCC) – the common calculus chain developed within EARLINET for the
automatic evaluation of lidar data from raw signals up to the final
products – was used. All stations sent in real-time measurements of a 1 h duration to the SCC server in a predefined netcdf file format. The
pre-processing of the data was performed in real time by the SCC, while the
optical processing was performed in near-real time after the exercise ended.
98 and 79 % of the files sent to SCC were successfully
pre-processed and processed, respectively. Those percentages are quite large
taking into account that no cloud screening was performed on the lidar data.
The paper draws present and future SCC users' attention to the most
critical parameters of the SCC product configuration and their possible
optimal value but also to the limitations inherent to the raw data. The
continuous use of SCC direct and derived products in heterogeneous
conditions is used to demonstrate two potential applications of EARLINET
infrastructure: the monitoring of a Saharan dust intrusion event and the
evaluation of two dust transport models. The efforts made to define the
measurements protocol and to configure properly the SCC pave the way for
applying this protocol for specific applications such as the monitoring of
special events, atmospheric modeling, climate research and
calibration/validation activities of spaceborne observations. |
