Update to high-performance data transfer services
Dear users,
You will be aware that many JASMIN and CEDA services were redeployed from RHEL6 to CentOS7 operating systems last year. The final few services - those deployed on physical servers in the JASMIN Data Transfer Zone - are now nearly ready for user access, so please note the following if you make use of these services:

JASMIN helps track the impact of climate change on UK birds
Over 600 different species of birds have been recorded in the UK to date[1] . For many of them formal monitoring is limited or absent. British Trust for Ornithology (BTO) ask for volunteers from the public to report nature observations from around the UK on mobile apps or online data entries such as BirdTrack . This is important because estimating bird distributions and population trends increases our knowledge about bird species or their habitats. Over 60,000 volunteers are involved recording bird species, resulting in a massive amount of data collected - in 2020 alone over 7.5 million records have been submitted to BirdTrack. Researchers at BTO have been using JASMIN to carry out statistical analysis on these data in order to better understand the reliability of Citizen Science data and the changes in UK bird populations that can be inferred from it.

Thankfully, our services have run largely as normal throughout the pandemic, but 10 months on, unfortunately, this ‘at risk’ status still stands. See below for details about how we anticipate it will continue to affect us and you.

CEDA 2020 highlights our work behind the scenes
Satellites and climate models are renowned for their ability to produce large amounts of data - as such, the CEDA Archive handles the largest datasets amongst the NERC Environmental Data Service (NERC’s collection of environmental data centres). Big data is not just a challenge for the CEDA Archive; the other NERC data centres are increasingly in discussions with researchers who have data that is too large for their infrastructures. As CEDA is at the forefront of development of infrastructure and services for large data volumes we have been sharing and integrating this knowledge across the NERC EDS. Here we highlight four different pieces of work that are ongoing behind the scenes to adapt to our big data challenges. ...
