The interactive map lets you view the projected changes in climate in NSW across different regions:

• view summarised information and a range of plausible climate change futures across NSW and ACT on maps and charts for 7 climate variables.
• information is presented as the change between a ‘historical baseline’ (1990 to 2009) and distinct future 20-year periods.
• examine these changes by region, by seasons or annually, and for 2 emissions scenarios.
• by clicking an individual grid cell, see how climate change may impact a specific location.
• download maps and tables for further analysis.

• The information on the interactive map has been tailored for general users. 
• The interactive map provides accessible climate change information in a visual format and provide users with data ready to be used in GIS/mapping applications.
• The Climate Data Portal is for  specialists who are experienced with, and knowledgeable of, climate modelling and the use of daily and monthly projections data in NetCDF format.
• You can access NARCliM1.0, NARCliM1.5 and NARCliM2.0 data on the Climate Data Portal.
• To learn if the Climate Data Portal is right for you, please visit the Climate Data Portal page on AdaptNSW.

• The interactive map was first released in 2014, with the release of NARCliM1.0. The current version of the interactive map has been updated with the latest high-resolution information and data from NARCliM2.0. 
• You can find more information on the differences between the NARCliM generations here
• NARCliM2.0 provides users a basis for understanding local-scale information and consider findings from the most recent IPCC reports.
• The new projections provide continuous data from 1951 to 2100 at a resolution of 4km in NSW.  By providing climate change information for multiple future periods users can better understand impacts and risks to assets, populations, and other important planning considerations.
• Users can now see how different future greenhouse gas emissions levels may affect the local climate. Projections are provided for low emissions high emissions scenarios.

• Climate change trends are generally similar between NARCliM1.0 and NARCliM2.0, but the magnitude of change differs. 
• Typically, the future climate projected for NSW by NARCliM2.0 is drier and hotter than the future climate projected by NARCliM1.0.

• Lord Howe Island and Norfolk Island are not included because they are outside of the 4 km regular grid domain available for the interactive map.
• If you require Lord Howe data, you can access via the National Computational Infrastructure Facility

• For comparability with analyses previously done, the same baseline was chosen. 
• Using the 1990 to 2009 baseline means that the change values displayed on the map are only relative to this period.

• Data has been simplified for readability.
• The projections for 2050 must be understood as representing averaged data for the period 2040 to 2059.
• Projections for 2090 representing averaged data for the period 2080 to 2099.

• All land area in NSW has a selectable grid cell. This includes grid cells whose area includes or covers the coastline.
• For coastal grid cells, the values may be slightly different to purely land-based cells due to the influence of the ocean.

• A map grid cell value represents an average of all 10 NARCliM2.0 model values for that grid cell. 

• The viewing options panel on the left side has been designed to move as you scroll down the page.
• Use the viewing options to select NSW, ACT or an NSW planning region.
• Select the climate index/variable you are interested in, and then the future period and emissions scenario.
• You can refine your search further to see changes annually or by season using the “Annual/Seasonal” selection tool above the map.
• Scroll down below the map to see averages of the 10 NARCliM2.0 models, and charts to see the range of model outputs that make up those averages.

• The interactive map lets you see climate change impacts (e.g., more hot days each year, changes in annual rainfall) at a specified location.
• After selecting the viewing options (variable, scenario, etc.), enter an address in the box at the top left of the map and click the "Search” button.
• Once the map zooms into the address, change the “View this map by” option from “Region” to “Grid”.  This will enable you to select a 4km grid cell and see what climate change looks like for that area. 

• In addition to the average of the 10 NARCliM2.0 models (thick blue line), the charts also provide the values for each individual model.
• Providing the spread of the 10 models can support a range of user needs.
• This information is vital because each model represents a plausible climate future. The ‘amount’ of spread between the models provides an indicative measure of the level of confidence/uncertainty - the smaller the spread, the greater the agreement between models and hence greater confidence in the projected climates.

• The light-coloured areas are large lakes, such as Menindee Lakes.
• This does not mean there is no data; it means that the change in the number of hot days over these large lakes is projected to increase by less than one day.

• Since there are very rarely ‘hot days’ – days 35°C and over – in winter in NSW, the averages over 20 years are close to zero.
• The map therefore displays as ‘white’, which is the colour representing less than 1 day.

• The device, browser and internet connection you have or are using may have an impact on map and webpage performance.
• The updated interactive map provides more data than the previous version, so it may perform differently.
• If the map doesn’t seem to refresh, try clicking it and moving it slightly. Performance should improve after the first few moments of use.

• Yes, the interactive map provides data packages for download.
• The data packages include ‘absolute/actual’ projected values for the 7 future periods within each of the 2 scenarios and the historical baseline period of 1990 to 2009 (used to calculate change).
• There is a “READ ME” file in each data package for more information on the GeoTIFFs.
• Users who have experience with netCDF data can access additional data from the Climate Data Portal
