In July this year ATMOS group attended the 14th Conference on Cloud Physics and 14th Conference on Atmospheric Radiation which were held together in Boston. The conference is organised by the American Meteorological Society every 3 years. It is one of the biggest conferences in Cloud Physics and Radiation field.

We were presenting two posters:

  1. How Can We Use Lidar And Radar To Monitor Aerosol-Cloud Interaction? presented by Karolina Sarna
  2. The satellite observation of drizzle in Stratocumulus clouds presented by Igor Stepanov

If you are interested in the recordings from the Conference or Extended Abstracts, have a look here:

On March 27th started the WaterLab Delft project.


This project is a collaboration between different organizations:
Gemeente Delft and Gemeente Rotterdam,
HH van Delfland and HH van Schieland en de Krimpenerwaard,
Unie van Waterschappen,
Hogeschool Rotterdam,
UNESCO-Institute for Water Education,
TNO, Deltares and TU Delft.

It consists in a better understanding of the water cycle in urban areas. It involves specialists of the water cycle and of the atmosphere and also students/pupils. It implies education and improvement of knowledge.

Edouard Martins from our group is currently working with three TU Delft students (David Kester, Ingo Schilken, Tim Gebraad). Their current work is to deal with the calibration of sensors mounted on several weather stations for a better accuracy of meteorological parameters (temperature, pressure, humidity, rain, wind, radiation) and for a better assessment of the impact of urban features (buildings, trees) in the measurement of these quantities.

The next step is to deploy several calibrated weather stations in high schools located in Rotterdam and Delft to have a better representation of the variability of these meteorological parameters in the urban areas of South Holland.

You can find more information in the official webpage of the project (in dutch).

More updates and pictures will come soon.

For the second year, staffs of our group (Christine Unal and Yann Dufournet) are going to give a course on atmospheric observation techniques. This course provides an overview of all up to date techniques which are currently used to observe and study the atmospheric components, from gas, aerosols to cloud systems. The course will be given in the 4th Quarter of this year, starting April 23rd. All Master students of TU Delft can enroll themselves via blackboard.

The Gordon Research Seminar and Conference: Radiation and Climate took place at the Colby-Sawyer College in New London, NH, near Boston, 5-12th of July, 2013. It brought together the atmospheric modeling and observing community from all over the world. Our PhD student Igor Stepanov attended with a poster presentation titled: Cloud lifetime and feedback observations. Practical conference with a lot of dedicated time for discussions, which went into overtime during the meal hours as well, thanks to the kitchen chef skills that kept us asking for more.

On Wednesday we had an atmosphere observations day. Our colleagues from Met Office Iceland, Richard and Hermann, have demonstrated a mobile X-band unit, used during the expected volcanic eruptions in Iceland. Students have deployed the radar and launched a radiosonde from a mobile launcher. We visited our weather stations to collect the data and 2 out of 8 were knocked out due to strong wind.

Students have placed the 4 weather stations near lake Myvatn to study the atmospheric variability within this region. Locations are around a hill approximately 500m elevation and two around it near its base. One station is placed on the coast of a small lake next to this hill. The next part of the measurements is planned for Thursday by hiking up one of the higher hills with the sensors.

14 MSc students from TU Delft and University of Reykjavik are together with our PhD students Lukas and Igor as instructors in Iceland, setting up atmospheric measurements, alongside geodetic measurements, during the next 2 weeks. They will use 8 identical Davis Vantage Pro2 weather stations to capture the spatial horizontal variability of meteorological parameters east of lake Myvatn. The area has many small hot lakes and very little change of the nature by humans, making it a challenge to reach strategically desired locations, that they will select. On Wednesday, our meteorological colleagues from Met Office Iceland will visit us for a radiosonde launch, with which the students will determine the cloud base height, and compare it with another 4 methods to do the same (ceilometer laser, stereo cloud cameras, tachymetry and the theoretical approach using the theoretical temperature lapse rate and ground measured dew point temperature) to see how they rank and which one is the most useful for specific purposes.

Group of all participants at the ITaRS start up work shop, 12-15.02.2013, Athens

From 13th till 15th February, the start-up workshop of the ITaRS (Initial Training for Atmospheric Remote Sensing) occured in Athens. At the workshop, 11 PhDs from different universities that were selected for this Marie Curie projects gathered together with their supervisors and representatives of the private sector companies. From the ATMOS group, Herman Russchenberg (standing in the middle in the back) and the PhD candidate Lukas Pfitzenmaier (sitting in the 3rd column in the middle) were participating. The focus of the workshop was about giving an overview on the different research topics of the fellows and network building.

The next official meeting of the ITaRS project will be during the first summer school in Bucharest end of September 2013. There, four post-docs will complete the group of the fellows. If your are interested in one of the post-doc positions check the ITaRS website . The application process is open till end of February!

The inaugurational address of Prof. Pieternel Levelt is available in Collegerama (in Dutch). Prof. Levelt speaks about satellite instruments used for the world-wide mapping of the ozone layer, air pollutants and greenhouse gases, and the insight that such measurements can provide into the complex relationships between air quality and climate.
