With the need for detailed surface temperature observations in mind we have planned a series of experiments over non-dense plant canopies to investigate the use of photogrammetry techniques. As before, in order to validate these models, detailed field observations are required. In order to account for these differences, again accurate modeling is required such as through the above mentioned multi-layer models or with several source type models such as SCOPE (Van der Tol 2009) in order to standardize observations. Additionally, at larger scales, canopy structure greatly influences satellite based surface temperature measurements as the structure impacts the observations which are intrinsically made at varying satellite viewing angles and solar heights. Such measurements would greatly improve multi-level canopy models such as NOAH (Chen and Dudhia 2001) or MuSICA (OgÃ©e and Brunet 2002, OgÃ©e et al 2003) where key surface temperature estimations, at present, are not tested. However detailed 3D surface temperature measurements or even profile surface temperature measurements are rarely made as they have inherent difficulties. As a key parameter, surface temperature permits the estimation of canopy exchanges using processes based modeling methods. Surface temperature of plant canopies and within canopies results from the coupling of radiative and energy exchanges processes which govern the fluxes at the interface soil- plant-atmosphere. However, a number of barriers have prevented its routine use in practice, such as the spatial and temporal resolution of remote sensing platforms, limitations in computing capac.ģD Surface Temperature Measurement of Plant Canopies Using Photogrammetry Techniques From A UAV.

May it reward you richly and leave an indelible imprint on many lives.Using plant canopy temperature to improve irrigated crop management 'Congratulations Lance! It's a beautiful piece of work. Partly because my friend did the book, but I love to hike and I am walking a spiritual path. 'I just finished reading your book for the first time and it was fantastic. Real and breathtaking, as it captures heart and soul from its viewer'. A wonderful time capsule commemorative work of art, photography and awe-inspired poetry, highlighting the Pacific Northwest. Inspiration comes from many different styles of work, each is of great interest to me.Ī preview of the book may be found here ******Ĭomments from others regarding this book Many thanks to the Flickr community for the positive comments on my photography during the last three years. I self published through Blurb and if you should get a moment, please drop in and have a look.

My son Cole, has the back cover and five other photographs in the book! In this book, one will find beautiful tributes from others, some poetry, a bit of historical writing and of course lots of photographs. I have been working on a book project with the Olympic Peninsula as my subject matter (wow, imagine that!).
