02 4570 1373 m.boer@westernsydney.edu.au Leaf area index (LAI) can be defined as the total one sided area of leaf tissue per unit area of ground and is a key derived parameter that is associated with water and light interception, radiation transfer, water and carbon exchange. Canopy cover can be defined as the fraction of ground shaded by the vertical projection of tree crowns. These measures may be used as proxies for actual canopy leaf area. Leaf area index is the preferred measure of cover for vegetation and is a key variable used in total biomass estimation and in carbon cycling prediction models. Indirect measures of LAI include digital photographic methods using flat or hemispherical images, referred to respectively as Digital Cover Photography (DCP) and (Digital Hemispheric Photography (DHP). LAI measurements are carried out at each SuperSite using the most appropriate method for the vegetation type present. Digital Cover Photography (DCP) was carried out at the Cumberland Plain SuperSite, Core 1 ha on 3 May 2017. The protocol generally followed the SuperSite Vegetation Monitoring protocol (http://www.supersites.net.au/publications-and-resources/resources-for-supersiteusers) using the Digital Canopy Photography method, except photo points were located at 5 m intervals along the 10 Gentry Transects (11 photos per transect). Photopoints were located at 10 m intervals along the 10 Gentry Transects (11 photos per transect).

Data Records. Picture location was transferred from field notes. Date and exposure bias were extracted from EXIF metadata for each photo. All information was exported as: “asn_cblp_veg_lai_20170503_data_table.csv” and submitted to TERN along with an accompanying data table description: “asn_cblp_veg_lai_20170503_data_deposit_form.docx”

Images were analysed with DCP-313 software written by Craig Macfarlane (CSIRO) to compute canopy LAI (MacFarlane et al. 2007). A single (blue) channel image is processed to create a grey-scale. Where RAW images are available, contrast stretching of the blue channel is achieved using the RAW2JPG MATLAB script before saving in JPG format prior to analysis (Macfarlane et al., 2014 Digital canopy photography: Exposed and in the raw. Agricultural and Forest Meteorology 197, 244‐253). Both DCP-313 and RAW2JPG executables are available from http://www.tern‐supersites.net.au/index.php/publications‐and‐resources/resources-for-supersiteusers

Coverage is restricted to the core 1 hectare of the Cumberland Plain SuperSite This patch of woodland is the core focus of the Cumberland Plain Supersite and also hosts the OzFlux, EucFACE and the core hectare. All photos were taken within the core 1 hectare, which is located circa 50 m due West of the flux tower. asn_cblp_veg_lai_20170503_image_details.csv LAI Data, Cumberland Plain SuperSite, May 2017 asn_cblp_veg_lai_20170503_image_details.csv 9580 1 #x0A column , ecogrid://knb/supersite.1028.1 cn=allusers,o=unaffiliated,dc=ecoinformatics,dc=org read uid=supersite,o=unaffiliated,dc=ecoinformatics,dc=org all date Date of observations yyyymmdd plot Plot ID Plot coord x Longitude.
