NAME¶

natgrid_params - This document briefly describes all the internal parameters of Natgrid.

DESCRIPTION¶

Each entry below includes the name of a parameter, its Fortran type (use the obvious equivalents for C), its default value, and a short description of the parameter.

´ADF´ - Integer - 0

Flags if the data file of algorithmic information for display with nnalg is produced - see parameter alg (0=no; 1=yes).

´ALG´ - Character - ´nnalg.dat´

File name for input to the algorithmic display tool nnalg (see parameter adf).

´ASC´ - Integer - 1

Flags if automatic scaling is allowed (0 = no; 1 = yes).

´bI´ - Real - 1.5

Tautness factor that increases the effect of the gradient estimates as bI increases.

´bJ´ - Real - 7.0

Tautness factor that decreases the breadth of the region affected by the gradient estimates as bJ increases.

´EXT´ - Integer - 1

Flags whether extrapolation is allowed outside the convex hull (0=no; 1=yes).

´HOR´ - Real - 0.1*(extent of X output grid)

Specifies the amount of horizontal overlap to be included outside of the current region when doing subblocking.

´IGR´ - Integer - 0

Flag indicating if gradient estimates are to be computed (1=yes; 0=no).

´MAGX´ - Real - 1.0

Scale factor for X coordinate input values.

´MAGY´ - Real - 1.0

Scale factor for Y coordinate input values.

´MAGZ´ - Real - 1.0

Scale factor for Z coordinate input values.

´MDM´ - Integer - 10

Maximum number of informational messages about duplicate point culls.

´NON´ - Integer - 0

Flags whether interpolated values are allowed to be negative (0=yes; 1=no).

´NUL´ - Real - 0.0

The value to be used on output for points outside of the convex hull when extrapolation is not allowed.

´RAD´ - Integer - 0

Flags if slopes and aspects are returned in radians or degrees (1=radians;0=degrees).

´SDI´ - Integer - 0

Flags if slopes and aspects are computed (0=no; 1=yes).

´UPD´ - Integer - 1

Flags if the output array goes from south to north or north to south (0=north to south; 1=south to north).

´VER´ - Real - 0.1*(extent of Y output grid)

Specifies the amount of vertical overlap to be included outside of the current region when doing subblocking.

´XAS´ - Real - 1.0

Contains the scale value for automatic scaling of X input values in the most recent interpolation call. For retrieval only.

´YAS´ - Real - 1.0

Contains the scale value for automatic scaling of Y input values in the most recent interpolation call. For retrieval only.

´ZAS´ - Real - 1.0

Contains the scale value for automatic scaling of Z input values in the most recent interpolation call. For retrieval only.
