This collection contains Air Temperature, Relative Humidity and Light measurement data from the RainOut Shelter (ROS) Facility 2, based at the Hawkesbury Institute for the Environment at the University of Western Sydney. The ROS facility is a series of six large, rain-sensing, automatic retractable roof rainout shelters, that allow field-based precipitation manipulation experiments on trees in Australia. Data included in this collection includes 5-minutely averaged data from the shelter facility and 30-second data from the associated control plot for the period July 2013*. The data collection (stored in the 'BagIt' file packaging format - see draft spec http://tools.ietf.org/html/draft-kunze-bagit-09) contains two files that, when unzipped, are in TOA5 file format. In addition a README.html file gives further details about each individual file. Mappings to definitions for each of the variable codes contained within these TOA5 files can be found at https://sites.google.com/site/hievuws/ (note that this url may eventually be migrated to a more permanent web location). *Some included data may not cover the month of May in its entirety and the user may therefore need to access preceding or subsequent collections. Note - this data is in raw format and as such has not yet been subjected to data cleansing. This will be done at a later date with the cleansed files uploaded as a separate entity.
