swath2grid

Recently I needed to convert swath data to gridded data. Most MODIS products come as gridded products which are properly geo-referenced / rectified. However, some low level products are provided as “swath” data which are the “raw” form when it comes to geo-referencing. Luckily most of these swath products do provide ground control point information to convert them from wobbly sensor output to a gridded […]

about complacency on politics

After past week’s election of Donald Trump I’ve decided to break what I consider an unspoken rule in science. Mainly, as a young scientist one does not discuss politics openly, nor take a hard line on issues, as it potentially jeopardizes your academic career. However, the US elections will have dire consequences for both domestic and global environmental policy and science in general, due to […]

virtualforest.io

Over the summer I created the Virtual Forest project. The aim of the Virtual Forest project is to immersively track the seasons using 360 photography and time lapse movies (once enough data is collected) of a forest in the North Eastern US. You can track the season in a regular browser, or on a mobile device supporting gyroscope feedback. For a complete immersive experience Virtual […]

Paramater estimation in R: a simple stomatal conductance model example

Most modeling approaches use some sort of optimization method to estimate parameters. These parameters are the knobs one has to turn to tune a statistical or mechanistic model exactly right to make it fit the data. Below I give a quick example of parameter estimation (in R) using a stomatal conductance (gs) model. A collaborator in the lab came to me with the question to quickly introduce […]

Pi power-over-ethernet

For a project of mine I needed power-over-ethernet (PoE) to be available on my Raspberry Pi. There are several reasons why one would want to use PoE. In my case I need a reliable network connection, and power couldn’t be provided consistently using solar or stand alone methods either. PoE combines both things without the necessity of having to run an extra power cable, proving […]
