Note: the steps with a * indicate steps that are currently performed by EOL.
Software programming languages are indicated in parentheses, and EOL
developed software is highlighted with a +.
The software tools listed here are meant to provide an overview of the known tools available for ELDORA processing. Software listed here is not necessarily supported by either EOL or the developer of the software. All questions regarding the use of a particular software package should be directed to the appropriate entity.
*Translate the raw ELDORA field format data into DORADE sweep
files.
View the sweep files with SOLO to see
if ground residual is zero
Repeat procedure if further correction is necessary
Edit the data to remove ground echo, noise, clutter, and radar
side-lobes, as well as velocity unfolding.
Known software tools:
SOLO+ - Interactive tool for
manual and batch editing of radar data. Contains many powerful features
for visualization and editing of both ground-based and airborne radar.
(C)
Automated ground removal algorithms over complex terrain for
NOAA P3 tail radar data
have been developed by Bousquet & Smull (2003),
but due to the
multiple frequencies used on ELDORA, they are not directly applicable.
Future efforts hope to resolve this.
Interpolate the data to gridded format.
Known software tools:
REORDER+-
Interpolates to cartesian or cylindrical (coplane) space. Output format
is CEDRIC or netCDF.
(FORTRAN & C)
Available interpolation schemes are Cressman, Exponential,
Uniform, and Closest Point
SPRINT - Interpolates to cartesian,
latitude-longitude, or
coplane space. Developed by Carl
Mohr and Jay Miller NCAR/MMM. Output format is CEDRIC.
(FORTRAN)
Uses bilinear interpolation
WindInterpolate -
Interpolates to cartesian grid. This
software is currently under development by John Gamache at NOAA's
Hurricane
Research Division. Output format is FORTRAN binary. (FORTRAN)
Uses bilinear interpolation.
Synthesize multiple gridded data files to get 3-dimensional
wind field and derived quantities.
Known software tools:
CEDRIC - Synthesis of multiple radar
grids using a
two-equation solution to derive U & V. W is obtained through upward
or downward integration of the mass continuity equation, or a
variational column approach. Use of an over-determined 3-equation
solution is also available with 3 or more radars. Developed by Carl
Mohr and Jay Miller NCAR/MMM. Output is CEDRIC
format. (FORTRAN & C)
Wind3_fill - Synthesis of multiple radar
grids using a
three-dimensional wind solver that includes the
continuity equation. A variational approach combined with a
loose-fitting continuity equation derives U, V, and W simultaneously.
This software is currently under development by John Gamache at NOAA's
Hurricane
Research Division. Output is FORTRAN binary. (FORTRAN)
Visualize resulting wind field and derived quantities.
Known software tools:
IDT - X-windows viewer for NCAR Graphics
gmeta files produced
during the CEDRIC synthesis.
Grid2ps+ - Creates
Postscript image files from
CEDRIC format files. Can be used to visualize REORDER and CEDRIC output.
Radarslicer - X-windows viewer for output from wind3_fill.
Developed by Peter Dodge and John Gamache at NOAA's Hurricane Research
Division.
