PhD or Postdoc Position in Satellite-Based Data Assimilation for Soil Moisture Estimation

Our team: http://ees.kuleuven.be/bwb/index.html

Soil moisture is a key variable in the water, energy and carbon cycle over land. The objective of this project is to merge large-scale land surface simulations with satellite-based microwave observations from the ESA Soil Moisture Ocean Salinity (SMOS) and NASA Soil Moisture Active Passive (SMAP) missions, using an advanced data assimilation scheme which corrects for both the random and persistent errors in soil moisture estimates. The improved soil moisture time series will help enhancing subsequent predictions of flooding, landslides, soil and vegetation carbon, deeper groundwater and the atmospheric boundary layer.

We are searching for an enthusiastic researcher with a keen interest in land surface processes to implement advances to a global land surface data assimilation system. You will be part of the Department of Earth and Environmental Sciences, Division Soil and Water Management, at the KU Leuven (Belgium), working under the supervision of prof. dr. ir. Gabrielle De Lannoy.

Profile
==========
- Master (for PhD position) or PhD (for postdoc position) degree in Hydrology, Civil or Environmental Engineering, Meteorology, Remotely Sensed Earth Observation, Physics, Mathematics, Computer Sciences, or equivalent
- Experience with data-processing applications such as Matlab/Python, IDL,GrADS, R, or other; interest in (for PhD position) or strong experience with (for postdoc position) programming and scientific computing
- Excellent motivation and grades
- Creative, critical, analytical and innovative mindset
- Ability to work independently
- Excellent written and oral communication skills in English

Offer
==========
- For PhD position: PhD scholarship for 4 years; support and training to PhD students through the Arenberg Doctoral School (https://set.kuleuven.be/phd)
- For postdoc position: 2-year position with a competitive salary; support in career development
- Multi-disciplinary and international professional environment
- Leuven is a charming historical university town, located in the heart of Western Europe

Interested?
==========
Applicants should submit their resume, along with a motivation letter and two names for possible references on-line. The starting date is October 1, 2016. For more information please contact prof. dr. ir. Gabrielle De Lannoy, tel.: +32 16 37 67 13, mail: gabrielle.delannoy@kuleuven.be.

You can apply for this job via the online application tool until September 1, 2016: http://www.kuleuven.be/eapplyingforjobs/light/53807202

Workshop announcement: « measuring high-wind speeds over the ocean »

Category : L2, L3, Ocean

On behalf of the organizing committee, I would like to draw your attention on the SMOS+STORM ESA project workshop

International workshop on measuring high-wind speeds over the ocean

15-17 November 2016, Met Office, Exeter

Overview:

A three-day workshop on the science and applications of ocean surface winds, with a focus on measuring high or extreme wind speeds. The workshop will be held at the Met Office headquarters in the cathedral city of Exeter.

Topics will include:

  • Satellite measurement techniques including new capabilities from SMOS, SMAP and AMSR2 sensors
  • Ground and airborne measurements
  • Core/operational applications and challenges e.g. hurricane/extreme forecasting, storm surges, waves
  • Air-sea applications and challenges e.g. seasonal/climate, upper ocean dynamics, air-sea interaction, biogeochemistry
  • Numerical Weather Prediction (NWP) applications
  • Numerical Ocean Prediction (NOP) applications

Organisers: Pete Francis (Met Office), James Cotton (Met Office), Nicolas Reul (IFREMER), Craig Donlon (ESA)

Further information on how to register for the workshop and submit an abstract and preliminary program is available from the link below:

Was 2015 a « DRY » year? and what about 2016?

Category : CATDS, L4

Several extreme drought events occurred in 2015 around the globe. At CESBIO, combining hydrological modelling and remotely sensed surface soil moisture from SMOS, we monitored a number of them. We used CATDS (Centre Aval de Traitement des données SMOS) products.

The aproach was to use our root zone soil moisture information derived from SMOS to infer a water scarcity index. Water scarcity in the root zone (0-1.5m) is actually an efficient early warning system for agricultural droughts.

droughts_2015_albitar

The figure above shows 5 of the major droughts which occurred in 2015. The small focus maps show the drought index during the drought events in each of the regions of interest. The losses caused by these droughts amount to billions.

So the next question is: are we facing long drought events that can impact food security at global scale?

In 2016 we may see even worse conditions. Our drought index seem to provide an alarming forecast. This was showcased by ESA during the Living Planet Symposium LPS2016 with this post using our latest root zone soil moisture map (see Water for crops – the SMOS root zone soil moisture).

We also produced the drought index map over North America for 2016 and it seems that after the Alberta fires and last year drought in the West coast of the US, the Eastern coast is now at risk. This forecast may change but it is clear that extremes conditions are breaking very old records, beyond the contribution of the El-Nino effect.

Changes in SMOS L3 TB

Category : CATDS, L3

Important information…

It was noticed by several users that our new RFI filter was overdoing things a bit (actually one of the flags was wrong) leading to a very reduced amount of available brightness temperatures.

We are working on this issue and already François and Stéphane have patched the bug and tests were carried out at CESBIO before implementation which is underway at CATDS.

The new products will have version number 310

Very soon the operational algorithm will release -less abusely filtered -  L3TB data (with more measurements thus) and we will also reprocess the whole data set (both L3TB and RFI).
