The Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE - NH) products provide measurements of daily sea ice extent and sea ice edge boundary for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection at both 1 km and 4
km grid cell sizes.

From the database, the group was able to calculate the geographical range, number of speakers, and rate of speaker decline for languages worldwide and map that data within square
grid cells roughly 190
km across, spanning the entire globe.
Yet to model tropical comvection
cells (Tstorms) responsible for Lindzen's adaptive IR iris,
grid cells need to be on the order of 10
Km (and certainly finer than 30).
This means in the Arctic region, GISS data is relatively coarse grained, as individual
grid cells above 80N may include station data interpolated out to as much as 1200
km, and are likely to show the higher short term variability which is characteristic of data from individual Polar stations.
Now we can start getting into more real climate models, but ghu, you need a
grid cell resolution of a few kilometers, not 250 or 100
km, and you need to analyse each
cell as its own navier - stokes thermodynamic / fluid dynamic system, not just a basic heat in vs heat out childs toy.
These convection
cells are at least one order of magnitude smaller than the smallest computable
grid cell (presently 1.1 degree or 120
km.
For example, the proxies in Gergis were screened against correlations with other
grid cells within 500
Km (a rationale for why 500, and not say 477, or 567 km was appropriate... we aren't told how many of the the time series correlated with adjacent grid cells, and how often the included or excluded times series DID NT correlate with adjacent grid cells... This kind of stuff is reported and considered when conducting an exploratory analysi

As detailed in appendix A, only records that were significantly (p < 0.05) correlated with temperature variations in at least one
grid cell within 500
km of the proxy's location over the 1931 - 90 period were selected for further analysis.
However, global model projections have coarse resolution, with
grid cell sizes of 200 × 200
km or more, reflecting limitations of the ocean GCM component of global coupled climate and ocean circulation — biogeochemical models.
Example: Let's say you have three 25 kilometer (
km) x 25
km (16 miles x 16 miles)
grid cells covered by 16 % ice, 2 % ice, and 90 % ice.
The atmospheric component of CM2.5 has similar physics as CM2.1, but uses
grid box
cells that are 50
Km on a side, versus approximately 200
Km in CM2.1.
