See Wikipedia heatmap definition.

GeoServer uses SLD to invoke the heatmap rendering transformation on a featuretype with point geometries and an attribute population supplying the weight for the points.
Web Processing Service (WPS) is an OGC service for the publishing of geospatial processes, algorithms, and calculations. The WPS service is available as an extension for geoserver providing an execute operation for data processing and geospatial analysis. WPS is not a part of GeoServer by default, but is available as an extension.

GEO FOUNDATIONAL TASKS: Session details. Ncdump -h geoem.d01.nc Ungrib.exe. If the Vtable files are in a different folder, they must be linked to @abel/WRF/WPS: ln -sf Vtable.ECSURF Vtable. If the input data is in a different folder than @abel:/WRF/WPS, link the gribfiles of your input to /WPS using linkgrib.csh:./linkgrib.csh.
The output is styled using a color ramp across the range or values in the output raster [0 .. 1].

SLD: - simply insert the attribute name to use for the values - here, POP2010.
This style is named AFREEMAN.TOWNSSURVEY_CTR_PT::Heatmap_POP2010

Towns with higher 2010 population have more red.

Adjustments can be made to parameters in the SLD. If radiusPixels value of 10 instead of 100 is used the map changes:

Radius controls the “spread” of the heatmap around each point.

In the SLD the pixelsPerCell parameter controls the resolution at which the heatmap raster is computed.
