FURTHER INFORMATION

Projects

FORClimateS

The project aims to aggregate and synthesize existing information on different spatial and temporal scales to provide decision-makers with relevant and robust information on short- and long-term risks for forests and forest functions and on adaptation strategies under different climate futures

PRO3FILE

To improve our assessment of ozone effects on forest ecosystems, we advocate the need (i) for further experimental and long-term monitoring studies and (ii) to develop physiological and demographic modelling tools.

Integrated Carbon Observation System (ICOS)

Integrated Carbon Observation System (ICOS) is a European research infrastructure to quantify and understand the greenhouse gas balance of the European continent and of adjacent regions.

Net Ecosystem Productivity - NEPSRI

Point dendrometer-based SRI data are collected within the project TreeNet and used to estimate NEP. The estimation is performed in near-real-time on the TreeNet processing platform (TreeNet_Pro) and needs temporally highly resolved SRI data and a site-specific leaf area index as input.

Below-canopy climate

Microclimate is a key factor influencing regeneration in forests. Particularly available light, water supply and temperature determine the success or failure of certain tree species. How will future climate change influence below-canopy microclimate and tree regeneration?

Data Science

Often I am being asked what I as a data scientist do all day long. Good question. I see myself at the source of data collecting and gathering in my technical role at the WSL. From installing sensors to cleaning them to making sure that the data is transferred to our database at the WSL, I collect about 250 million data points per year.

However, it doesn't stop there because my focus continues towards making the data not only accessible from a technical point of view but also making the data usable. This whole process is a crucial point which is often underestimated. In the end, the physical upload of a csv file may take a couple of minutes, but describing, cleaning, flagging the data may take months. Mike Driscoll defined data munging as the "painful process of cleaning, parsing, and proofing one's data", which I can only confirm.

Below a figure undermining my statements above. The result is based on a survey conducted by CrowdFlower. The main article was published on Forbes. The main finding is that 60% of data scientists answered that they spend most of their time on cleaning and organizing data.
