The additional data rescued by HCLIM helps improve early reconstructions, but doesn't fundamentally change the large uncertainties due to sparse sampling.

Admittedly a bit slow on the uptake, but i am enjoying diving into HCLIM: nature.com/articles/s41...
A dataset of weather stations with pre-1890 data.
This includes ~450 temperature stations whose data was not previously available in the normal digital archives.

The best way to reduce those large uncertainties would be to bring in more historical data for better global coverage.
Data rescue and digitizations efforts like HCLIM, can play a big role in trying to make more early weather data available.

My awesome colleague Abraham Torres ran a bunch of simulations with our new regional climate model #HCLIM + showed that 2.5km resolution was really crucial to resolve precipitation from ARs on ice shelves and ice sheet. Cloud processes + foehn are also crucial to get the energy budget correct

Very happy to see this awesome paper out by @marlenkolbe.bsky.social and my @dmidk.bsky.social colleagues (including @martinstendel.bsky.social) on atmospheric rivers in Antarctica and implications for melt and precipitation.

Model performance and surface impacts of atmospheric river events in Antarctica - Discover Atmosphere
There is increasing evidence that atmospheric rivers (ARs) drive extreme precipitation and melt events across Antarctica and that these impacts are more accurately captured in high-resolution models. ...

Exactly the kind of study that makes me rejoice in science. And now to make a new land cover surface type for The Model™️ #HCLIM.. theconversation.com/temperatures...
Temperatures in a patch of Antarctic moss can vary as much as an entire mountain range
The moss beds in Antarctica are like miniature forests – they create their own climate.

I will be going out in a small team (as part of @precise-project.bsky.social project) to collect SMB data, repeat some old shallow cores and do radar lines, and we're also looking at snow redistribution processes. But our work is also high res regional climate modelling with HCLIM for projections
