Vegetation greenness (NDVI)
Change date: Early 2019

Changes to the Cooperative Observer Network
Scheduled update: 1 August 2015
From 1 August 2015 a number of manual observation sites will record a single, daily observation and will no longer have 3 pm observations. The majority of sites are unaffected by this change.
The Bureau's observations network includes a broad range of meteorological observations equipment to meet the needs of its forecasting and severe weather warning services, and provides data for the National Climate Record.
The Bureau continually assesses its network of meteorological observations to ensure the most effective and cost efficient network is in operation. As the availability of automated observations has increased, the number of manual observations has decreased.
In some cases data from nearby Automatic Weather Stations may be accessed on the Bureau's website as an alternative.

Seasonal climate outlook update
Scheduled release date: 22 May 2013
The Bureau of Meteorology is updating the model it uses for the monthly Seasonal climate outlook
The 3-month outlooks will be based on a dynamical model, which uses the physics of the atmosphere, oceans, land and ice interactions to calculate the probability of above (or below) normal rainfall and temperature. Previously, outlooks were based on a statistical model, which uses history as a guide to the next season's rainfall and temperature.

Monthly rainfall data quality control changes
Scheduled release date: 11 October 2011
Climate Data Online monthly rainfall information is being updated. A recent data review has resulted in changes to the classification of quality controlled monthly-total rainfall data. Around 500,000 records (5.5% of total records) will have their status changed to ‘not quality controlled’. The total precipitation value should remain unchanged. These records are pre-2000, with greater than half pre-1950. Their status was down-graded because they lacked historical detail.
During the review process a small quantity of daily rainfall data were recovered enabling updating and additional monthly totals to be calculated.
