Months of getting equipment ready have finally cumulated in 10 days field work at the scenic Summerland House Farm. Prof Barry Osmond (pictured) and I spent ten days in the field trying to understand photosynthesis in both the inner and outer canopies of Avocado trees. We were running all our equipment from four large car batteries which we charged overnight and lugged out to our field site each day. During the ten day campaign we were met with everything from clear summer days to golf ball sized hail and we often found ourselves rushing to the field site to ensure none of our equipment got wet. Overall though a successful field campaign with lots of promising data collected and a big thankyou to all the welcoming staff at Summerland Farm House and Alstonville Country Cottages.
Satellites provide a key method for measuring properties of the biosphere, atmosphere and hydrosphere on global scales. In particular, in recent years the detection and quantification of solar induced fluorescence (SIF) as a means to quantify plant growth and productivity has been a key goal of both NASA’s OCO-2 mission and the proposed European FLEX mission. However, the processes driving SIF are not fully understood.
