PhD in atmospheric physics & meteorology. Research Associate @ Bern University of Applied Sciences (BFH) & Delft University of Technology (TU Delft). Studying clouds using remote sensing and data-driven methods. Also a PALM model system developer.
I'm happy to share that I've completed my PhD in meteorology!🥳
On Tuesday, I successfully defended my thesis "Modelling and measuring transport processes within urban surface layer at high spatio-temporal resolutions" at the Faculty of Science of @helsinki.fi .
Thanks to everyone involved!

I’m happy to share that I’ve started in a new position as Research Associate at Bern University of Applied Sciences BFH! 🇨🇭
I'm working on the UrbanAIR project (www.urbanair-project.eu), focusing on urban heat and clouds, using remote sensing and data driven methods.

I finally submitted my PhD thesis "Modelling and measuring transport processes within the urban surface layer at high spatio-temporal resolutions" for examination a week ago on Tuesday.
This also marks the end of my time at Univ. of Helsinki, I'm currently spending my remaining holidays in India!

The energy balance closure of the model can be written like this. This represents all the flows of energy from or to the model and all the places where it can be stored within the model. The sum of all the flows and storages should be zero, i.e. the energy should be conserved.

After N hours (where N is far greater integer than I would be comfortable with) of debugging, my single-layer urban surface model for the PALM model system (a LES model, see palm.muk.uni-hannover.de) is 2 W/m^2 from full energy balance closure. So close!

Blogikirjoituksessa (www.foreca.fi/meteorologil..., julkaistu 30.11.) viitataan ECMWF:n 10 vrk ennusteeseen. EC:n pintalämpötilan parviennuste Helsinkiä lähinnä olevalle hilapisteelle kyseiseltä päivältä antaa jo osviittaa, että ennusteen epävarmuus on suuri tiistaista eteenpäin.

Mitään erikoista ei tapahtunut, mutta ennusteen epävarmuuden kommunikoinnissa medialle epäonnistuttiin jälleen. Oma henkilökohtainen mielipiteeni on, että Forecan blogikirjoitukset ovat nykyisellään huono lähde ja lähtökohta sääuutisointiin.

Recently, there hasn't been much social media friendly stuff to post on my work as I've been implementing the remaining technical aspects and fixing bugs of my single-layer urban surface model implementation for the LES model PALM. Now I'm finally able proceed to sensitivity testing & evaluation!
