PLEASE READ CAREFULLY BEFORE APPLYING: The GRASP Summer School is free for everyone who wishes to register and can attend in person. Due to the high volume of applications we receive, once your registration form has been submitted, we will confirm in the following days whether you have been selected to participate in this edition of the GRASP Summer School in Valladolid.
The GRASP Summer School 2026 is organized for its third edition in the city of Valladolid (Spain) from June 29th to 30th 2026, within the framework of the MSCA Staff Exchange funded project GRASP-SYNERGY.
This event provides intensive training on the Generalized Retrieval of Atmosphere and Surface Properties (GRASP), which is the first unified algorithm developed for characterizing atmospheric properties from a wide variety of remote sensing observations and the synergy of them. The program is structured to combine theoretical overviews with hands-on practical applications:
The first day focuses on the GRASP concept and overview, led by Oleg Dubovik and David Fuertes:
-
Technical sessions cover the forward model overview and numerical inversion techniques.
-
Hands-on practical sessions include running the GRASP forward model and understanding software settings.
-
Specific software overviews and cloud-based applications are demonstrated by the technical team.
-
A dedicated use case on sun-photometers concludes the first day.
The second day explores diverse applications and instrument synergy, led by multiple GRASP fellows:
-
Presentations cover various applications in GRASP and the synergy between sun-photometers and lidar.
-
Practical workshops focus on data preparation for lidar and nephelometer data.
-
Specialized lectures address error estimates and satellite-based observations.
-
The school concludes with hands-on training for multi-instrument space observations and satellite applications.
Participants are encouraged to visit the GRASP-OPEN website to explore products and documentation to learn more about the algorithm and its scientific applications prior to the event.
