Climate information, projections, tools and data

File naming convention

Data files are named using the following convention:

<variable>_<domain>_<host name>_<rcp>_<run>_<model description>_<version>_<frequency>(_<season aggregation method>)_<time period>(-<change type>).nc


<variable> is the climate variable code:

  1. epanave = average pan evaporation at the surface
  2. evspsbl = evapotranspiration at the surface
  3. hurs = relative humidity at 2 m above the surface
  4. pr = precipitation at the surface
  5. rsds = solar radiation at the surface
  6. sfcWind = average wind speed at 10 m above the surface
  7. tas = average daily temperature at 2 m above the surface
  8. tasmax = maximum daily temperature at 2 m above the surface
  9. tasmin = minimum daily temperature at 2 m above the surface

<domain>  The name of the 'domain' or geographic area covered by the dataset:

  1. VIC-5 = all data for VCP19 are from the VIC-5 domain

<host name> is the name of the 'host' model which was downscaled. Model names follow the format, INSTITUTION-MODEL:

  4. MOHC-HadGEM2-CC
  5. NCC-NorESM1-M

<rcp> = Representative Concentration Pathway (more detail ):

  1. RCP4.5 ("medium emissions")
  2. RCP8.5 ("high emissions")

<run> = a descriptor that indicates the run, initialisation and parameterisation versions of the simulation:

  1. r1i1p1 = run 1, initialisation 1, parameterisation 1

<model description> = the details of the model used to produce this specific dataset:

  1. CSIRO-CCAM-r3355 = CSIRO's Conformal Cubic Atmospheric Model published run r3355.
  2. CSIRO-CCAM-r3355-PctlChg-wrt-1986-2005-Scl = percentile changes relative to 1986-2005 from CCAM used to scale observed data.

<version> = version of the model as described by model description:

  1. v1 = version 1

<frequency> = the frequency (time-step) of the dataset (in datasets with multiple frequency data, the highest frequency or smallest time-step):

  1. day = daily
  2. mon = monthly

<season aggregation method> (when relevant) = the way the data (as described by 'frequency') have been aggregated:

  1. seasavg - averaged across the 'season' (which in this context can be month, 3-month season, 6-month season or annual)
  2. seassum - summed across the 'season'

<time period> = the range of years to which the future data relate. For:

  1. change data = the period over which the future change has been averaged.
  2. application-ready data = the period over which the time-series data extend.

<change type> (change data only) = type of change calculated for the time period:

  1. clim-abs-change-wrt-1986-2005 (climatology given as absolute change (e.g. in mm, Wm-2, °C) with respect to the 1986-2005 average).
  2. clim-perc-change-wrt-1986-2005 (climatology given as percentage change with respect to the 1986-2005 average).

.nc is the file extension for NetCDF files.
