DEFINE REGION/DEFAULT saveStores the current default region under the name "save". There are several documents in $FER_DIR/doc regarding gridfiles and TMAP format (e.g., about_grid_files.txt). Ch3 Sec2.3.28. notice that they are not properly ordered VARIABLE : SPAWN("ls -1 tmp/fcst_*.nc") SUBSET : 11 points (X) 1 / 1:"tmp/fcst_10.nc" 2 / 2:"tmp/fcst_11.nc" 3 / 3:"tmp/fcst_1.nc" 4 / 4:"tmp/fcst_2.nc" 5 /

Specifying the context of the input variable explicitly e.g. LET/UNITS="M/S"/TITLE="Meridional Wind"/D=2 VWND = vwnd_in[D=2,GXY=vwnd[d=1],GT=vwnd[d=1]@MOD] See the variables we defined. It must have the scattered-data direction along a Z or T axis. This is the variable we are putting onto the grid.

Define a set of locations. This command is in many ways the equivalent of using a descriptor file or multi-CDF dataset.  Each method for creating a virtual dataset has advantages. See the discussion under SCAT2GRIDGAUSS_XY. You can change PPL ORIGIN and PPL AXLEN only after SET VIEW is issued.

It returns the function value at the grid point closest to each point in XPTS, YPTS. http://fiftysixtysoftware.com/root-mean/what-is-a-good-root-mean-square-error.html If no title is specified the text of the expression will be used as the title. (See also SET VARIABLE/TITLE.) DEFINE VARIABLE/UNITS= Specifies the units (in quotation marks) of the variable LET xx = x[gx=salt]yes?

MISSING( temp, -999 ) replaces missing values in temp with –999 MISSING( sst, temp[D=coads_climatology] ) replaces missing sst values with temperature from the COADS climatology Ch3 Sec2.3.18. LET x1 = if lons lt `xx[[email protected]]` then lons+360yes? DEFINE REGION/X xonlyStores the current default X axis limits, only, as region xonly. 3) yes? this content See the discussion of grid-changing functions.

DEFINE AXIS/X=lo:hi:delta axis_name The limits may be in longitude, latitude, or date format (for X, Y, or T or F axis, respectively) or may be simple numbers. Converting to NetCDF 11. DEFINE AXIS/T="15-FEB-1982":"15-FEB-1984":48 tnewyes?

Examples: DEFINE REGION 1) yes?

let p = (obsrved-model) yes? SHADE u_on_newgrid Ch3 Sec2.3.37. See the discussion of grid-changing functions. Result Axes: X Inherited from F Y Inherited from F Z Inherited from ZAXPTS T Inherited from TAXPTS The gridding algorithm is discussed under SCAT2GRIDLAPLACE_XY.

DEFINE GRID/LIKE=temp[D=ba022]/T=sst[D=nmc] gnmc3dDefine grid gnmc3d like temp from data set ba022 but with the same time axis as sst from data set nmc. 3) yes? show data/brief ! RHO_UN( salt, temp, P ) For example: ! have a peek at these guys ACOS COS(X) Trigonometric arccosine (0,pi), in radians.

But variance of the climatological months are not that common to have :) ...yes? equivalent to the above yes? DEFINE AXIS/Y=-30:10:1 yaxyes? ! Always reread the most recent version from the file.yes?

This title will be used to label plots and listings. For a full description of all this, see section 3.1.8 in the Users guide - http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/variables-xpressions/VARIABLES#_VPINDEXENTRY_277 Scroll on down in this section to section 3.1.8.2, Attribute Keywords We will be using let r = q[l=10:[email protected]] !for OND yes? Ch3 Sec2.3.3.

DEFINE AXIS/T=25:125:5/UNITS=minutes axt5min DEFINE AXIS/CALENDAR= Allows for non-Gregorian calendar axes. In the case of XSEQUENCE(sst), for example, the input grid for SST is lonlatnormaltime whereas the output grid is abstractnormalnormalnormal so all axes of the input are replaced. DEFINE REGION/DX=-5 xonlyStores the current default X axis limits minus 5 as region xonly. 4) yes? YPTS y-locations of scattered input triples, organized as a 1D list on any axis.

Grid-changing functions create a potential ambiguity about region specifications. DEFINE REGION/DI=/DJ=/DK=/DL=/DM=/DN=/DX=/DY=/DZ=/DT=/DE=/DF= Specifies a change in region relative to the current settings (=lo:hi or =val). Often "Z[gz=zaxis_name]" is used for the third argument. SCAT2GRIDLAPLACE_XT SCAT2GRIDLAPLACE_XT(XPTS, TPTS, F, XAXPTS, TAXPTS, CAY, NRNG) Use Laplace/ Spline interpolation to grid scattered data to an XT grid.

C) and pressure P(dbar), moved adiabatically to a reference pressure REF(dbar). DEFINE DATA/AGGR/F/TITLE="Climate FMRC" fmrdat = 1,2,3,4,5,6,7,8,9,10yes? LET xnew = if x1 gt `xx[[email protected]] then x1-360 else x1 yes? There is only one cutoff in the algorithm once the XSCALE and ZSCALE mapping is applied.

yes? cancel data/allyes? Define potential temperature! The DEFINE DATA command will define an abstract E axis, and the members of the aggregation will be listed on this axis in the order they are given on the command
