MetInterp Interpolation and Adjustment Settings

MetInterp interpolation and adjustment settings control the distribution of gage data spatially. These settings support running interpolation with multiple methods. These can be specified in a table, where each row is a different interpolator. For each interpolator, there is a Spatial Interpolation Method, Vertical Adjustment Methods, Temporal Data Sampling Methods, which can be selected with drop-down menus within the table. Vertical adjustments have a common set of settings. Therefore, two interpolators using Lapse Adjustment will use the same terrain grid and lapse rate. If different vertical adjustment settings are needed for a given analysis, this will require separate control files.

Item	Description
1	Add spatial interpolator to the list of spatial interpolators.
2	Remove the selected spatial interpolator.
3	Table for editing spatial interpolators. In this table the user can change the interpolator name, set the Spatial Interpolation, Vertical Adjustment, and Temporal Sampling methods.
4	Field for specifying the distance beyond the convex hull of the points that extrapolation can be performed.
5	Bias grid file specification.
6	Bias DSS grid record. This is only enabled if the Bias Grid File is a DSS file.
7	Terrain grid file specification
8	Terrain DSS grid record. This is only enabled if the Terrain Grid File is a DSS file.
9	Static lapse rate specification field.
10	Unit selection for the lapse rate.
11	Checkbox to specify that the lapse rate should be computed from the data. When selected, items 8 and 9 become disabled.
