Last Monday, during the @copernicusecmwf.bsky.social C3S User engagement workshop within the #CzechSpaceWeek, I got a chance to present our work on the evaluation of precipitation datasets in Czechia.
The paper is currently under review, but the preprint is available here:
doi.org/10.13140/RG....

The event was a joint effort of four #COSTActions: #3DForEcoTech (groud-based LiDAR), #PANGEOS (remote sensing), #CLEANFOREST (tree ecophysiology and ecology) and #ARiF - Augmented Reality In Forestry.

Huge thanks to #PANGEOS for supporting my participation!

#ConnectedByTrees

💡@markuseichhorn.bsky.social's keynote on interdisciplinarity reinforced my postdoc goal to step beyond Earth Observation and collaborate across disciplines: to learn more by knowing less.

I also briefly showed my peers how SAR time series can support forest monitoring during the PANGEOS section.

🌳 Last week I participated at the Interdisciplinary Summer School on Forest Ecosystems in Oxford with 40+ participants from 25 countries.
5 intensive days with a field trip, lectures, hands-ons & even keynotes in pubs.

Thanks @mokros.bsky.social and his team for the organization!

In my poster, I also shared new improvements where I incorporated temporal features, applied snow masking and extended the training dataset timeline to five years, which significantly boosted the accuracy of our #MachineLearning models!

During the ESA #LPS2025 in Vienna last week, I had the chance to present our work on estimating time series of vegetation indices for Central European #forests using Sentinel-1 #SAR, ancillary data and #ML approaches.

Last week, I participated the #CLMSGA2025 in Kraków, Poland, where I presented the MMTS-GEE tool to generate spatially and temporally aligned SAR, optical, topographic and meteo. data. I also showed two case studies using MMTS-GEE:

🌧️ Which #precipitation dataset is the most accurate on a daily basis in Central European conditions?

We tried to answer this question evaluating 10 satellite-based and #reanalysis precipitation datasets on a daily basis for #Czechia (2001-2021).

✅ Achieved temp. resolution of up to 240 measurements/year using SAR-based VIs with 2 S1 satellites in 2021 [soon to be restored with Sentinel-1C]
✅ Early disturbance detection: within 4 days vs 35 days with optical indices

Can we estimate optical vegetation indices and biohpysical parameters for forests using #Sentinel1 #SAR & ancillary data? We tried to answer this in our latest paper in @bigearthdata1.bsky.social With the help of #machinelearning we generated SAR-based NDVI, EVI, LAI & FAPAR

Great to see it in action. Looks cool!
It reminded me that for larger countries, I should add a selection for smaller administrative units. I will try to implement it soon.

🌍 I have created an interactive #GEE app to generate #Sentinel2 cloud-free mosaics for any country and timeframe, defined by the user.
