    The far north Queensland microclimate (FNQ-microclim) is an ongoing long-term microclimate monitoring project from across five tropical rainforest sites (Daintree Rainforest SuperSite, Cape Tribulation; Daintree Rainforest SuperSite, Cow Bay; Rex Range; Mt. Lewis National Park; and Mt. Bellenden Ker), located within an elevation range of 40 - 1550 m a.s.l. Microclimate parameters include: a) air temperature (about 15 cm above ground), b) near surface temperature at the interface between soil and air (less than 1 cm above ground), c) top soil temperature (about 8 cm below ground), and d) top soil moisture (up to 10 cm below ground). Data are recorded every 15 minutes using the TMS-4 sensors (Temperature Moisture Sensor, T.M.O.S.T s.r.o, Prague, Czech Republic).

    <br>This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.5.0) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).</br> <br>Wombat State Forest site is a secondary re-growth forest that was last harvested in 1980. Dominant tree species are <em>Eucalyptus obliqua</em> (messmate stringybark), <em>Eucalyptus radiata</em> (narrow leaf peppermint) and <em>Eucalyptus rubida</em> (candlebark) with an average canopy height of 25&nbsp;m. The understorey consists mainly of patchy grasses and the soil is a silty-clay overlying clay. The forest is managed by the Department of Sustainability and Environment and management includes selective harvesting and prescribed burning regimes. The climate of the study area is classified as cool-temperate to Mediterranean with cold and wet winters (May-August) and warm and dry summers (December-February) with temperatures between 1 and 30&nbsp;°C and mean annual air temperature of 12.1&nbsp;°C. Annual rainfall is approximately 871&nbsp;mm (142 year long-term average). Coherent automated measurements of soil greenhouse gas fluxes (CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O) were collected using a trailer-mounted mobile laboratory - Fourier transform infra-red (FTIR) spectrometer from 2010 to 2016. Measurement height was originally 30&nbsp;m but increased to 33&nbsp;m in January 2017.</br>

Data were processed using PyFluxPro (v3.5.0) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER).</br> <br>The flux station site is located within an area of dryland agriculture. The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 152&nbsp;m and mean annual precipitation at a nearby Bureau of Meteorology site measures 650&nbsp;mm. Maximum temperatures range from 12.3&nbsp;°C (in July) to 29.7&nbsp;°C (in February), while minimum temperatures range from 10.4&nbsp;°C (in July) to 26.8&nbsp;°C (in February).</br> <br>The instrument mast is 4&nbsp;m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall and net radiation are measured. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry.</br>

The surrounding area is dominated by broadacre farming practices. The vegetation cover is predominantly pasture. Elevation of the site is close to 330&nbsp;m. Climate information comes from the nearby Pingelly BoM AWS station 010626 (1991 to 2016) and shows mean annual precipitation is approximately 445&nbsp;mm with highest rainfall in June and July of 81&nbsp;mm each month. Maximumum and minuimum annual rainfall is 775 and 217&nbsp;mm, respectively. Maximum temperatures range from 31.9&nbsp;°C (in Jan) to 15.4&nbsp;°C (in July), while minimum temperatures range from 5.5&nbsp;°C (in July) to 16.0&nbsp;°C (in Feb).<br /><br />

Elevation of the site is close to 250&nbsp;m and mean annual precipitation at a nearby Bureau of Meteorology site is 640&nbsp;mm. Maximum temperatures range from 28.4&nbsp;°C (in June/ July) to 39.1&nbsp;°C (in December), while minimum temperatures range from 11.2&nbsp;°C (in July) to 24.4&nbsp;°C (in December).</br> <br>The instrument mast is 5&nbsp;m tall.

Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out at the site in September 2008. Biomass harvest measured: mean live biomass 0.00&nbsp;gm<sup>-2</sup> (standard error: 0.00), mean standing dead biomass 163.42&nbsp;gm<sup>-2</sup> (standard error: 16.73), mean litter biomass 148.99&nbsp;gm<sup>-2</sup> (standard error: 21.32), total mean biomass 312.40&nbsp;gm<sup>-2</sup> (standard error: 30.80).

Pine Hill Station is a functioning cattle station that has been in operation for longer than 50 years. However, the east side has not been stocked in over three years. The site is a mosaic of the primary semi-arid biomes of central Australia: grassy mulga woodland and <em>Corymbia/Triodia</em> savanna.The woodland is characterised by a mulga (<em>Acacia aneura</em>) canopy, which is 4.85&nbsp;m tall on average. The soil is red sand overlying an 8&nbsp;m deep water table. Elevation of the site is 553&nbsp;m above sea level, and the terrain is flat. Mean annual precipitation at the nearby (30&nbsp;km to the south) Bureau of Meteorology station is 305.9&nbsp;mm but ranges between 100&nbsp;mm in 2009 to 750&nbsp;mm in 2010. Predominant wind directions are from the southeast and east.</br> <br>The instrument mast is 10&nbsp;m tall. Fluxes of heat, water vapour and carbon are measured using the open-path eddy covariance technique at 9.81&nbsp;m. Supplementary measurements above the canopy include temperature and humidity (9.81&nbsp;m), windspeed and wind direction (8.28&nbsp;m), downwelling and upwelling shortwave and longwave radiation (9.9&nbsp;m). Precipitation is monitored in the savanna (2.5&nbsp;m). Supplementary measurements within and below the canopy include barometric pressure (2&nbsp;m). Below ground soil measurements are made beneath Triodia, mulga and grassy understorey and include ground heat flux (0.08&nbsp;m), soil temperature (0.02&nbsp;m - 0.06&nbsp;m) and soil moisture (0 - 0.1&nbsp;m, 0.1 - 0.3&nbsp;m, 0.6 - 0.8&nbsp;m and 1.0 - 1.2&nbsp;m).</br>
