BILO Gridded Climate Data: Daily Climate Data for each year from 1900 to 2012

## **Abstract** 

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on the known details at the time of acquisition.

The BILO gridded data set contains daily fields of selected meteorological variables at 0.05 degrees resolution for the whole Australian continent, including Tasmania.  It was obtained by CSIRO for use in the Australian Water Availability Project.  In addition to daily data fields, some aggregates at monthly and annual intervals have been created.

The variable is daily rainfall. Current data is updated daily by automatic download from the BoM website. Periodic updates (approximately every 6 months) of the dataset include new data and reprocessed data in immediately preceding years. These different revisions are distinguished by an element in the file names "bYYMM" which gives the last two digits of the year and the two digit month corresponding to the revision delivery date. These data represent the snapshot of current data as at 14/10/2013.

## **Dataset History** 

The data are a snapshot of the climate dataset known as BILO which represents the data as at 14/10/2013. CSIRO maintain a copy of the data as licenced though the Australian Water Availability Project.  The BoM version is constantly updated and revised when new data are obtained, when errors in data are identified and when interpolation routines are revised.  Therefore there may be difference in the values of some grid cells in the current BoM data compared to this snapshot held by CSIRO. The current BoM archive for these data are listed in the URLs below.
