hubUtils vs topocast: at a glance
What is hubUtils?
The hubverse's shared plumbing, tracking schema versions and converting output types.
hubUtils is the low-level dependency the rest of the hubverse builds on: schema version tracking, config file reading, example test hubs, and conversion between forecast output types. Its releases are small and cadenced to the hubverse schema itself, with a version bump arriving whenever the config schema advances. The recent work is performance rather than surface.
What is topocast?
New R package downscaling coarse climate rasters onto fine terrain, now five times cheaper per call.
topocast is a young R package — first released in June 2026 — that downscales coarse rasters onto fine terrain using moving-window regression, with the relationship expressed as a formula over layer names. Its defining implementation choice is summed-area tables, which make the cost of estimating coefficient grids independent of the window radius. Three releases in six weeks have taken it from first publication through real-workflow fixes to a substantial performance restructuring.

hubUtils
0.0ANALYTICS
The hubverse's shared plumbing, tracking schema versions and converting output types.
◆ Current state
hubUtils is the low-level dependency the rest of the hubverse builds on: schema version tracking, config file reading, example test hubs, and conversion between forecast output types. Its releases are small and cadenced to the hubverse schema itself, with a version bump arriving whenever the config schema advances. The recent work is performance rather than surface.
◆ Where it's heading
The through-line is that this package absorbs whatever the schema is doing — v5, then v6 with target-data configuration, each arriving with matching accessors and example hubs so the sibling packages can be tested against something real. convert_output_type() is the one piece of genuine computation here, and it has now been optimised by roughly an order of magnitude, suggesting it is being used at scales the original implementation did not anticipate. Everything else is accessors and fixtures.
◆ Prediction
Expect the next substantive release to track the next hubverse schema version, with any independent work concentrated on convert_output_type(), the only performance-sensitive function in the package.
topocast
2.5ANALYTICS
New R package downscaling coarse climate rasters onto fine terrain, now five times cheaper per call.
◆ Current state
topocast is a young R package — first released in June 2026 — that downscales coarse rasters onto fine terrain using moving-window regression, with the relationship expressed as a formula over layer names. Its defining implementation choice is summed-area tables, which make the cost of estimating coefficient grids independent of the window radius. Three releases in six weeks have taken it from first publication through real-workflow fixes to a substantial performance restructuring.
◆ Where it's heading
Development is being driven by running the package against real datasets — the second release names CHELSA and SRTM as the source of its three fixes — and the third is a direct response to multi-response calls repeating work. The arc is the ordinary one for a new method package: publish the method, then discover that real inputs have more responses, more coordinate-system edge cases, and more repeated structure than the initial design assumed. Coefficient grids being exposed as output suggests the local regression parameters, such as lapse rate, are as interesting to users as the downscaled values.
◆ Prediction
Expect continued work on multi-response and time-series throughput, and more coordinate-system and input-validation handling as the package meets further real climate datasets.
