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.
