Cooperation between Spain and Iran in the framework of SDS-WAS

by Enric Terradellas last modified Jul 24, 2017 10:13 AM

Dr. Saviz Sehat Kashani, Academic member of Atmospheric Science and Meteorological Research Center (ASMERC) of the Islamic Republic of Iran Meteorological Organization (IRIMO), participated in the training course on “Atmospheric Aerosols and Mineral Dust”. The training course was organized by the WMO Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) Regional Centre for Northern Africa, Middle East and Europe, hosted by tha State Meteorological Agency of Spain (AEMET) and the Barcelona Supercomputing Centre. It was held at the AEMET's Izaña Atmospheric Research Centre (IARC) from 20th June to 6th July 2017.

During the event, Dr. Sehat received information from Dr. Emilio Cuevas on the SDS-WAS program and specifically on mineral dust observation, complementarities and synergies between SDS-WAS and the WMO Global Atmospheric Watch (GAW) program

Dr. Africa Barreto introduced the main concepts of lidar technique and presented the lidar program conducted at the IARC to characterize the vertical structure of the Saharan Air Layer (SAL). Dr. Carmen Guirado was in charge of detailing operational and research aspects of solar photometry techniques and specifically the AERONET program and the European ACTRIS project. She provided practical information on sun photometry calibration by using the handheld Calitoo (Tenum) sunphotometer, and on activities carried out at the optical laboratory.

Dr. Sehat had also the opportunity to work with Tenum engineers, who were in Izaña for a calibration campaign in the framework of ACTRIS. She performed with them some instrument calibrations and received first-hand information on Calitoo's new software.

The new zenith-looking narrow-band radiometer-based system (ZEN) for dust aerosol optical depth monitoring and its measurement methodology was explained by Fernando Almansa, who is the main developer of this new instrument (Almansa et al., 2017).

Detailed information on techniques, methodologies, and science of in-situ aerosol observation was provided by Dr. Sergio Rodríguez and his team (Dr. Elisa Sosa and Dr. Isabel García), including filters weighting, calibration activities (an special aerosol intensive summer campaign was held at the Izaña Observatory) and maintenance and calibration works in the aerosol research laboratory "Prof. Joseph M. Prospero". Special attention was paid to the atmospheric mineral dust monitoring program using different instrumental techniques and methodologies.

Dr. Sehat had also the opportunity to participate in the training course entitled “ACE20: Future North Atlantic Atmospheric Observation Systems. Assessing the legacy of ACE2” held at the Mencey Hotel in Santa Cruz de Tenerife from 4 to 6 July 2017 . Dr. Sehat met there eminent scientists, experts on atmospheric aerosols and dust

Finally, a half-day special session was dedicated to discuss with several IARC researchers on potential collaboration between IRIMO and AEMET in the framework of SDS-WAS.

On the return trip to Tehran, Dr. Saviz Sehat made a one-day stop in Barcelona, where she had the opportunity to meet researchers from the Barcelona Supercomputing Center: Dr. Sara Basart and Dr. Enza Di Tomaso, with whom she discussed on several aspects of SDS-WAS and assessed the opportunity for Iran to join the SDS-WAS activities in model validation and mineral dust characterization in Iran, a key region, about which there is very little information, but which is vital to improve atmospheric dust predictions.

AEMET thanks IRIMO for providing the necessary resources to enable Dr. Sehat to participate in the training course, and to Dr. Sehat for her very enthusiastic and fruitful SDS-WAS training course and course follow-up.
