Descripció del contingut i pla d'activitats:
Satellite-based atmospheric Earth observation missions, and in
particular EarthCARE of the European Space Agency (ESA), have
intense validation needs over a limited lifetime, yet validation
resources themselves have a need for long-term continuity.
EarthCARE, ESA's and JAXA's Earth Cloud, Aerosol and Radiation
Explorer mission, is scheduled to be launched in spring 2024 and
addresses the need for a better understanding of the interactions
between cloud, radiative and aerosol processes that play a key
role in climate regulation and thus is of the general interest of
ACTRIS, ATMO ACCESS, and relevant communities.
The student will integrate data obtained from several
instruments: Micro Pulse Lidar, High-power Lidar, Space-born
lidar. The comparison will be used in the Calibration /
Validation exercise of EarthCARE satellite.
1) Brief literature review
2) Software environment selection
3) Development of basic functions: dowload files, data selection,
graphical plot.
4) Graphic User Interface development.
Overview (resum en anglès):
The main objective at this project is to create a software that makes the
Comparation/Validation exercise between two LiDAR (Light Detection and
Ranging) systems. Those systems, although they are equivalent conceptually,
they apply different technology. The first system was developed by
CommSensLab group from UPC (participants in the creation of EARLINET); on
the other hand, SigmaSpace, another business under Godard Space Flight
Center specifications (belonging to NASA), that manage the MPLnet network
following the Micro-Pulse LiDAR concept. Both have the same purpose; they
measure the atmosphere aerosols. The comparation between the MPLnet
LiDAR system and the one that will be used at the EarthCARE mission will be
realized in a later phase, outside the scopes of this project. The software
pretends to intercompare the Earlinet lidar from UPC with a MPLnet system.
To achieve this objective, it has been used MATLAB tool, since we can find
some functions that facilitate the work when we are reading the type of file is
used to save all the information obtained from the lidar systems. Lidar systems
use the format NetCDF to save all the data. There have been created some
functions to make the main code cleaner as possible. Also, it has been used
GUIs (Graphic User Interface) that are the windows that the user can see when
is using the software.
It has been achieved an automatic download of all the necessary files that the
user needs to start the comparation between the systems. When the files are
downloaded, plots can be generated where the user can see the comparation
between the systems in specific parameters that are interesting to compare.
Those parameters are backscatter, extinction, volume depolarization, particle
depolarization and range corrected signal. Also, it has been implemented the
option to create a Word report with all the plots selected by the user and each
one of the plots with a caption that describes the necessary information. The
figures used at the report are saved in a folder with all the formats that MATLAB
