Return a sequence of grids. A grid is a coordinate space and cube of data. Grids have a name, attributes, and a 2d tensor. When creating the grids, you can choose the time-axis and the z-axis to choose. -1 means choose the entire dimension; defaults to 0 meaning all of the returned grids is 2 dimension. Code is written with the assumtion that a non-negative integer will be chosen for the time-axis and the z-axis as this will increase the dimensionality of the data tensor. Returns a sequence of grids where a grid is: {:name :attributes map of name->attribute :coordinate-system GridCoordSystem :data tensor :data-reader FloatTensorReader (allows arbitrary indexing and ad-hoc algorithms) }

Open a netcdf file. The return value is tracked via 'tech.resource/track. If the user wishes to release the memory early they can call .close on the object.

inclusive-exclusive-HRRR-bounding-boxes-from-grid clj

(inclusive-exclusive-HRRR-bounding-boxes-from-grid hrrr-grid)

Take the y min,max values from the grid projection and project every point on the x axis. Build two bounding boxes (y min,max) from the projected data

Ignoring time, query a grid pointwise by lat-lon. Returns only closest match. Takes a grid and a sequence of [lat lng] tuples. Returns { :missing-value ##NaN, :fullname "Temperature_surface", :abbreviation "TMP", :level-desc "Ground or water surface", :level-type 1, :cell-lat-lngs - reader of [lat lng] tuples of the center points of the grid cells :values - (float-array n-elems) }
