Atmospheric scientist (postdoc, 2+2 years) position methane satellite research, Netherlands Institute for Space Research (SRON), the Netherlands (deadline 1st March 2026)
We are looking for an ambitious, highly motivated, and result driven (postdoctoral) scientist with experience in interpreting atmospheric (satellite) observations.
SRON is the space research expert institute in the Netherlands, developing and using Earth observation satellite instruments for climate and air quality research. SRON is the (co-) Principal Investigator institute for a.o. the Dutch satellite instruments TROPOMI, SPEX-One, and TANGO.
You will be working on our TWOS (Targeting Waste emissions Observed from Space) project together with GHGSat and the Global Methane Hub.

Ph.D. candidate, Internal climate variability under climate change in Europe, Department of Atmospheric Physics at Charles University, Prague, Czech Republic (deadline 5th March 2026)
Internal climate variability (ICV) constitutes an essential part of natural climate variability and is inherent to the Earth's climate system. It is manifested as spatiotemporal modes of variability like ENSO, NAO, etc., but it is also present in time series of observed meteorological elements at all spatial scales. ICV also constitutes an important source of uncertainty in climate model outputs, especially regarding the occurrence of climatic extremes. Furthermore, the ICV characteristics are expected to change with ongoing anthropogenically forced climate change.
The proposed project aims to deepen our understanding of how the ICV will interact with externally forced changes in the statistical distribution of selected climatic variables. Consequences of revealed changes for the occurrence of extreme climatic events will also be investigated.
The research will focus on Europe, with emphasis on central Europe. The analysis will rely on existing climate model outputs from CMIP and LongRunMIP initiatives, as well as Single model initial-condition large ensembles (SMILEs). Specific goals will be discussed and elaborated with selected candidate, depending on their background, interests and skills.
The successful candidate will join the Climate research group and participate in the current research projects, including Czech Science foundation project “Internal climate variability over Europe“ (25–15855S), OP JAK “Georisks” (CZ.02.01.01/00/22_008/0004605) and TAČR PERUN (SS02030040).
The research will be supervised by Eva Holtanová, but the cooperation will embrace also other group members. The Ph.D. study of the candidates will be fully funded, partly from the mentioned projects and partly as a regular monthly stipendium, together making about net 1500 EUR/month income
Requirements:
- Master-of-Science-equivalent degree in meteorology and/or mathematics/statistics, environmental physics or general physics with fulfilled courses on climatology, statistical methods and basics of climate modelling.
- The candidate should have experience with Unix / Linux scripting and programming skills in Python or R.
- A creative mind-set for scientific research
- Willingness to interact with international science community
- Strong communication in English language (spoken and written)
Deadline for applications is 5th March 2026.
