Introduction

The information presented here comes from the results of an online user survey conducted by the Australian Bureau of Meteorology (hereafter the 'Bureau') in February 2005. The aim of the survey was to investigate what types of weather information members of the public use to assist them in making weather-dependent decisions, and how they access this information. The survey also examines the Bureau's performance in meeting the weather information requirements of the Australian public, considering aspects such as the accuracy, timeliness and usefulness of weather services.

It is important for the Bureau to have an understanding of how people access and use weather information and services, and to know what they think of the accuracy, timeliness and usefulness of weather services. This information assists the Bureau with future planning of products and services, and is also used in regular reports to the Australian government.

 

Weather Information Used To Make Decisions

Reference: question 1

In making decisions based on or influenced by the weather, most survey respondents indicated that in the past month they had sought information about rain and maximum temperature.

Figure 1 shows a comparison of weather elements of interest to Victorian survey respondents.
