-------------------------------------------------Ancient history: for reference------------------------------------------------------------------

These images are provided to convey a notion of the strengths and weaknesses of BRAN, which we are still assessing ourselves. For selected examples, links marked [SPIN1] show output from the spin-up run of OFAM, during which the same atmospheric forcing was applied, but no assimilation of altimeter or other data was done.

To view the animations you might need a fli movie player.

Updates
1 Sept 2005: Commenced SPINUP4, which has revised initial and boundary forcing, to address the (erroneous) warming trend of BRAN1.
27 Sept 2005: From model day 7 March 1997, the parameters of the mixed layer scheme are altered to reduce the thickness of the mixed-layer, which was evidently still too thick.
23 Aug 2006: First test of delivering graphics for viewing using Google Earth.
20 July 2007: BRAN2.1 completed, and is clearly a big improvement on BRAN1.
2 August 2007: Public launch of the Bluelink Forecasts.

Away from Australia
BRAN is a global reanalysis, but it is not expected to be of much use outside the high-resolution area.
