Abstract

This package contains automatic weather station readings from a site in Tarawi Nature Reserve, first set up in May 2015, replacing an older manual rainfall gauge. Between 1996 and 2011, 53 experimental sites were established on dune crests and upper slopes, of which 29 are located in Tarawi Nature Reserve, 16 are in Scotia Sanctuary and 8 are in Danggali Conservation Park. After initial censuses in three consecutive years (before and after prescribed fire) or two consecutive years (after wildfire), sites are revisited approximately every five years. A synopsis of related data packages which have been collected as part of the Mallee Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/mallee.

Funding

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.

Method Step 1
Description
Plot set-up

As of May 2015 a new advanced automatic weather station has been deployed at Tarawi site T2005/2. There were 12 manually monitored rain gauges across Tarawi Nature Reserve and Scotia Sanctuary, but these have now have been phased out.

Data from the automatic weather station is downloaded annually.

Sampling
Study Extent Description

Automatic weather stations were established at Tarawi Homestead and Scotia Sanctuary homestead in 1994. They record precipitation, temperature, relative humidity and wind speed and direction. Prior to that time, rainfall records had been maintained since 1941 by visually monitored rain gauge. Four additional visually monitored rain gauges were established in Tarawi NR in January 1997, a further five were established in May 2001, and two were established in Scotia Sanctuary in September 2007. As of May 2015 a new advanced automatic weather station has been deployed at Tarawi site T2005/2. The exisiting rain gauges have been phased out.

Sampling Description

Data from the automatic weather station is downloaded annually.

Relative humidity: the ratio of the air's water vapor content to its capacity (percentage). Air temperature and pressure are used to calculate the amount of water vapor in the air as a percentage of the amount the air is capable of holding. The reading is taken at the end of the 120 minute interval.

Dew point: the temperature to which air must be cooled for saturation to occur (100% relative humidity), providing there is no change in water vapor content. Average temperature and an approximation of the outside humidity during the 120 minute interval are used to calculate the due point. The average outside humidity is calculated by averaging the outside humidity for the current 120 min interval and the previous interval.
