Reanalyses – A sharing of juicy tidbits

No DaSH meeting this week

Hi DaSHers,
Just writing to let you know there will be no DaSH meeting this week as we are lending our lecture theatre booking to Zanna Chase who is hosting a group of school kids on Friday morning.

DaSH will be back next week with Mike Sumner who will be telling us all about mapping tips and tricks in R and elsewhere

See you next week.

DaSH Meeting on August 22

Hi DaSHers
Probably most of you have heard about Reanalyses, but how many of you actually know what the term really means? This week’s speaker, Andrew Klekociuk from the Australian Antarctic Division, is going to enlighten us all about what is a Renalysis and what they are good for. His talk is entitled “Reanalyses – A sharing of juicy tidbits* and gory details**”. I shall allow Andrew to explain the title in his own words.

According to Reanalyses.Org, in a reanalysis, ‘observations and a numerical model that simulates one or more aspects of the Earth system are combined objectively to generate a synthesized estimate of the state of the system’.

In this discussion, I’ll give an overview of reanalysis methods, and outline some of the more widely used reanalyses and their application, focussing mainly on the atmosphere. Bring along stories of your experience (or inexperience) with reanalysis data, and we’ll discuss the joys and pitfalls of using this type of data for climate studies, environmental case studies and measurement evaluations, amongst other things.

Selected definitions…
* a choice or pleasing bit of anything, as gossip.
** to tell all the small details about something that is unpleasant or interesting in a shocking way.

ALSO: No DaSH meeting next week as we have lent out our lecture theatre for hosting a school excursion. The week after (September 5) Mike Sumner from AAD is going to give us a talk. In the following weeks we have Ben Galton_Fenzi and Marty Hidas to look forward to.

Where:

IMAS Aurora Lecture Theatre – it’s the big lecture theatre on the left as you walk into the waterfront building foyer – 20 Castray Esplanade, Battery Point,  next to CSIRO.

When:

DaSH Meeting for August 15

Hi DaSHers
No doubt you have all heard about the cloud. Possibly some of you are even using some form of cloud for back up of data form your phone or other media device. Have you ever thought about using the cloud for serious computing? This week Brendan Davey from TPAC (Tasmanian Partnership for Advanced Computing) will give us an introduction to NeCTAR, the eCloud and how it can be used to facilitate and assist our research (and let’s be honest, who doesn’t want to tell their friends that they are using a virtual supercomputer for their analyses?).

ALSO: Coming up next week we have Andrew Klekociuk from the Atmospheric Physics section of the Australian Antarctic Division. If you have an idea for a DaSH talk then please put your hand up.

Where:

Dash Meeting on August 8

Hi DaSHers

This weeks we have the exciting Will Hobbs who will be telling us all we need to know about accessing and using model output from the global climate models reported upon in the 5th Assessment Report of the IPCC. Will’s talk is entitled An Introduction to dealing with multi-model ensembles (or how I learned to stop worrying and love CMIP5).

Because he is organsed Will has even provided an abstract
The Coupled Model Inter-Comparison  Project v5 (CMIP5) is unprecedented in the scope of standard experiments, the number of climate models included, and the range of output variables. This makes it an incredible (free!) resource for all manner of researchers, but also brings with it some serious logistical and even philosophical challenges to trip up the unwary. This talk will be a practical guide for people new to using very large multi-model ensembles, and will include tips on initial strategies and planning; finding, accessing and managing data; possible hazards when processing data; and finally some ongoing hot topics on how to interpret results.

ALSO: Coming up next week we have Brendan Davey from TPAC who will be expounding on the virtues of using the ecloud, followed by Marty Hidas from IMOS showing us how we can use the IMOS data portal to aid our research and Andrew Klekociuk from the Antarctic Division talking about Reanalyses.
