Today is all about making sure everyone gets to the site, although we make the most of the hot sunshine, by getting our first scan underway early.
In the morning, we selected several additional plots in order to get a wide variety of different species and densities of stands in both coniferous and deciduous areas. We now have a target of 10 sites including the three core plots that we have already covered.

Today, Mark and I are joined by Rachel Gaulton from Newcastle University, who worked with SALCA for a year before I started and has been heavily involved in the calibration and creation of processing methodologies for SALCA and Richard Casey from University College London, who has started a PhD focusing on computer simulation of multi-waveform terrestrial lidar data and who is using some data from SALCA in his research.

Alongside the SALCA scanning, which will take priority this week, several experiments and field measurements have been discussed. Amongst these, an examination of the variability of hemispherical photography as a method for gap fraction analysis is started today and involves photos taken every day at plot 1 to cover a range of weather conditions. These images will then be processed by several different people to assess how much results vary.

We manage to get three scans in today at three different pine stands before retiring to our accommodation for the evening.
