Climate data rescue activities being undertaken in Australia

Updated: Nov 21, 2016 11:30 IST

Washington D.C. [USA], Nov. 21 (ANI): A new research draws attention to recent data rescue efforts undertaken in Australia to study the climate and climate change, in the southern latitudes.

The article has been published in published in Advances in Atmospheric Science journal.

Long-term weather data is the backbone of almost all research into climate change and variability.

The recovery of historical instrumental data is a well-established practise in the Northern Hemisphere, where observations are available for the past several centuries in many regions.

In the Southern Hemisphere, the currently available set of climate observations generally only begin in the early to mid-20th century. This makes it harder to study the climate change.

The study was conducted by Dr. Linden Ashcroft (University Roviara I Virgili, Spain) and her co-authors from the UK and Australia.

The data rescue efforts being undertaken in Australia range from international initiatives such as the South Eastern Research Climate project (SEARCH), to volunteer organizations, working with families who have uncovered their grandfather's long-lost weather diaries.

According to Ashcroft, these extended sets of weather observations can

-improve future climate projections

-validate palaeoclimate records from tree rings and ice cores

-put our current climate into a long-term context, helping scientists identify what is natural, and what is human-induced climate change.

"The stories of these meteorological pioneers deserve to be shared, and the data they painstakingly collected more than a century ago are still very useful today." says Ashcroft.

The data they have uncovered are already contributing to international datasets that are in turn being used to build global models of the atmosphere.

The addition of even one new weather station can dramatically improve the accuracy of these models for the Southern Hemisphere.

More observations are now being found in ship logbooks, settler's journals and colonial records in the Southern Hemisphere.

"Through our efforts and those of others, and we are slowly shedding more light on our important climatic past. " says Ashcroft. (ANI)
