This metadata is associated with an environmental raster layer describing the longest number of consecutive days with <1mm rainfall across Australia (further description below). The layer was created by Alejandra Morán-Ordóñez in 2015 as part of a project on modelling species responses to extreme weather. A paper associated with this project is currently in press & this metadata will be updated to reflect the availability of the original data when the article is published.

This project used a clipped version of the original data, focused on the Central Highlands Regional Forest Agreement Area of Victoria, Australia. The original raster was created as follows: "Interpolated daily and monthly climate data at 0.05° spatial resolution (~ 5-km) were obtained from the Australian Water Availability Project for the period 1977 – 2012 (Raupach et al. 2009, 2012). Temperature data were corrected with an adiabatic lapse rate of 0.00645°C m-1 (Moore 1956, Sturman and Tapper 1996) from the original 0.05° values to a resolution of 0.01° (~1 km) based on a digital elevation model (DEM) resampled from its original 0.0025° to 0.01° resolution (GEODATA 9-second DEM v.3, Geoscience Australia). [...]  From the daily weather data we calculated [...] indices describing [...] the maximum length of dry spells (maximum run of sequential dry days; rainfall < 1mm)[...]"
