- Abstract
-
The Victorian Alpine Plot Network Climatic Data Package contains climate data collected at a sub-set of the 481 long term monitoring plots situated in the Australian Alps. The climate data monitoring data comprises average hourly air temperature and location data for each of the snowpatch monitoring sites. This is part of a much larger dataset that spans from 1944, when plot were set up to document long-term changes in ecosystem composition and structure in relation to disturbance (see methods for more information). The Victorian Alpine Plot Network research plots are revisited on a 2–10 years basis. A synopsis of related data packages which have been collected as part of the Victorian Alpine Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/victorian-alpine

Since 2012 this project has been part of the Long Term Ecological Research Network (LTERN). This work was supported by the Australian Government’s Terrestrial Ecosystems Research Network (www.tern.org.au) – an Australian research infrastructure facility established under the National Collaborative Research Infrastructure Strategy and Education Infrastructure Fund–Super Science Initiative through the Department of Industry, Innovation, Science, Research and Tertiary Education.

Plot set-up
The Victorian Alpine Plot Network Climatic Data Package contains climate data collected at a sub-set of the 481 long term monitoring plots which have been established in Australian Alps and in Tasmania. The sampling regime within the Victorian Network generally consists of multiple randomly positioned transects within sites, (rather than ‘plots’ sensu stricto), with each site, and/or transect geo-located. Point quadrats are taken at fixed intervals along each transect. Point quadrats are taken using a 4 mm diameter steel pin inserted vertically into the vegetation. The number of transects within sites, and sampling frequency varies from annual to decadal, depending on site and purpose.

Data collection
The climate monitoring involved the collection of a suite of climatic variables, including average hourly air temperature recorded using two temperature data loggers (DS1920 Thermochron®, Maxim Integrated Products, 120 San Gabriel Drive, Sunnyvale, CA). This protocol was established during the 2011-12 season. Loggers are set to highest resolution (0.06°C) and are start delayed so that readings are recorded on the hour. We place both loggers 50 mm above the bare soil surface, attached to a wooden stake (100 mm wide) and facing south, hence shaded. Where temperature data from the two loggers is not within a 0.5°C range of each other we exclude the data which is consistent with procedures followed by the Australian Bureau of Meteorology. These data are downloaded every five (5) months before rollover occurs (4028 readings gives 167 days at the settings recommended).
Note the equivalence of the following site codes in accompanying spatial data:
1) AussieDrift_A; AussieDrift_B = ADRIFT_SNP
2) BakersSpurSNPA = BAKER_SNP1
3) CopeHutSNPA, CopeHutSNPB = COPEHUT_SNP
4) CopeSNPA, CopeSNPB, MtCopeSNP1_A, MtCopeSNP1_B, MtCopeSNPB, CopeSNP_A, CopeSNP_B = COPE_SNP1
5) HeathySpurSNPA, HeathySpurSNPB = HEATHY_SNP1
6) NelseNorthSNP2A, NelseNorthSNP2Asecondsetloggers, NelseNorthSNP2B = NELSENTH_SNP2
7) SpionKopjeSNPA, SpionKopjeSNPBonground = SPION_SNP1
