Join our enthusiastic Numerical Weather Prediction (NWP) team at the Research and Development of Weather and Climate models department (RDWK) as a Verification and Development Specialist! We are looking for a talented and motivated individual to make impactful contributions to the HARMONIE-AROME NWP system. Your work will play a key role in our collaboration with Denmark, Ireland, and Iceland through the United Weather Centres West (UWC-West) initiative.

What will you be doing?You will actively contribute to the preparation of the HARMONIE-AROME NWP system for incorporating data from the Infrared Sounder onboard the Meteosat Third Generation satellite, scheduled for availability between Q1 and Q2 2025. This involves investigating methods to optimize the use of Hyperspectral Infrared data.

Your key responsibilities will include exploring the viability of using Transformed Retrievals (TRs) in the HARMONIE-AROME 4D-Var data assimilation. You will collaborate closely with the UK MetOffice and the Eumetsat Numerical Weather Prediction Satellite Application Facility (NWP SAF) to assess the robustness of the TRs approach by comparing forecast skills between the UWC-W and UK MetOffice NWP systems. The work entails a total of 4 month secondment to the UK MetOffice.

Specifically, your role will encompass three main tasks:

  • Implementing the TRs approach in the HARMONIE-AROME 4D-Var.
  • Generating TRs from Infrared Atmospheric Sounding Interferometer (IASI) radiances using existing software at the UK MetOffice, and assimilating these TRs and their observation operators in HARMONIE-AROME 4D-Var to validate this new approach.
  • Extending the NWP SAF 1D-Var package to estimate TRs and observation operators, along with atmospheric profiles, surface fields, cloud top pressure, and cloud fraction.

Additionally, you will document the technical implementation for generating and assimilating TRs and the results from the assimilation experiments. You will also refactor code to produce TRs and observation operators embedded in the NWP SAF 1D-Var package.

This gives you energyYou'll be at the forefront of advancing the HARMONIE-AROME Numerical Weather Prediction (NWP) system, contributing significantly to our collaboration with Denmark, Ireland, and Iceland in the United Weather Centres West (UWC-West) initiative. Your role will involve exploring innovative methods to enhance Hyperspectral Infrared data usage, including the viability of Transformed Retrievals (TRs) in 4D-Var data assimilation.

You'll work closely with the UK MetOffice and the Eumetsat NWP Satellite Application Facility (NWP SAF), implementing TRs in the HARMONIE-AROME 4D-Var code, generating TRs from Infrared Atmospheric Sounding Interferometer (IASI) radiances, and validating these through assimilation experiments.

Your efforts will directly improve weather prediction models, impacting public safety, agriculture, and disaster preparedness. Engaging with a dynamic team and documenting your results, you'll continuously expand your expertise and drive meteorological advancements.

Would you like to know more?We understand that you might want to learn more about this position. Therefore, feel free to contact Ben Wichers Schreur, deputy department head via +316 8133 6849.He will be happy to assist you!

Our unique task is the gathering of information about the atmosphere and the subsurface and the translation of that information to risks for society.

Would you like to learn more about how we strive to make our high-quality knowledge and information in the area of weather, climate, and seismology operationally available? You'll read more about it on our website.

  • A MSc in meteorology, environmental sciences, computer science (or similar)
  • Experience in satellite data analysis, radiative transfer or data assimilation
  • Strong programming skills, ideally in Python, Fortran and UNIX shell scripting or equivalent
  • Fluency in English is required and a basic knowledge of Dutch is preferred

You recognize yourself in the following characteristics:

To excel in this role, you must possess a strong background in meteorology or a related field, and extensive experience in analyzing data from the HARMONIE-AROME system would be an advantage. You need to be a critical thinker with innovative problem-solving skills to enhance weather prediction accuracy. Effective communication skills are vital for collaborating with international partners. Additionally, you should be able to document your technical work clearly. Being steadfast in scientific integrity and balancing societal needs with scientific standards will also be key to your success.

The department Research and Development of Weather and Climate models (RDWK) investigates and develops research tools for weather and air quality prediction applications and climate research. We work on detailed physical processes, data assimilation, long term climate projections and practical applications including storm surge forecasts and statistics of extremes. RDWK participates in international projects directed towards a variety of weather and climate related research and development areas. The department has a strong international network.

The department performs its activities in collaboration with partners like ACCORD, EC-Earth, the European Centre for Medium-Range Weather Forecasts and universities. We work for the national road and water authority Rijkswaterstaat, the Ministry for Infrastructure and Water Management, the Dutch research funding organisation (NWO), the European Copernicus programme and other European research programmes; and on servicing the operational weather forecast centre, climate scenarios and strategic research. The department collaborates with the other KNMI departments.

Royal Dutch Meteorological Institute (KNMI)

The weather is temperamental, the ground moves and the climate changes. For our safety and prosperity, we need to know what risks and opportunities this brings. And: how we can best prepare ourselves. The Royal Dutch Meteorological Institute (KNMI) is the national knowledge and data center for weather, climate and seismology. Reliable, independent and focused on what the Netherlands needs. For a safe Netherlands that is prepared for the impact of weather, climate and earthquakes.

We use our core values - Development, Cooperation and Relevance - to achieve our ambition, both within and outside KNMI, nationally and internationally. We develop our knowledge and expertise and work together to create a single KNMI that makes a difference to society!

Talent as the basis, diversity as the strengthThe KNMI is an inclusive organization.
