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.
