Analysis Date:
Valid Input: Any
valid date listed on the form.
Description: Global analysis fields are based on
the latest 10 days of Jason
and T/P, and 17 days of GFO and 35 days of ERS-2 and Envisat sampling,
if available. See Satellite
Dates for more information. Earlier analysis fields, if available,
may be accessed using the pull-down menu.
Geographical Region of Interest:
Valid Input: Longitude:
0.0 to 360.0 Latitude: -62.0 to 72.0
Description: This allows you to select a region of
the world where you would like to collect the sea surface height
anomaly data. All values are in degrees, and all longitude values are
in East Longitude. Minimum values may never exceed maximum values for
longitude or latitude. Note that smaller regions generate smaller files
and thus take less time.
Bathymetry:
Valid Input: 0 to
11000
Description: This option provides the capability of
editing data in shallow water from your plot (units are in meters).
Only data in ocean regions deeper than the input value will be plotted
or contoured.
Contouring Options:
Valid Input: Any
selected radio button
Description: This
option allows contours and/or anotation to be visible.
Degree Format:
Valid Input: Any
selected radio button
Description: Here
you can choose the output format to be used when
annotating map boundaries. Choose between the four formats:
- Longitudes go from 0 to 360, latitudes from -90 to 90.
- Longitudes go from -180 to 180, latitudes from -90 to 90.
- Longitudes are unsigned 0 to 180, latitudes unsigned 0 to
90.
- Longitudes are unsigned 0 to 180 with letters E or W
appended, latitudes are unsigned 0 to 90 with N or S appended.
Color Palette:
Valid Input: Color,
Grayscale, None
Description: This
variable defines the color palette to be used in your
plot.
- Color - This uses a continuous rainbow color
palette
between the minimum and maximum range of data values.
- Grayscale - This uses a grayscale color palette
between the minimum and maximum range of data values. Not
implemeted at this time.
- None - This turns all color mapping off.
Inverval:
Valid Input: 0 to
100 (0 disables
contours)
Description: This
variable allows you to define a contour interval and/or
tick marks on the color bar (units are in centimeters). If a color
scheme other than "None" is chosen, contours will overlay the color
graphics map.
Range of Data Values to Apply Color
Palette:
Valid Input: -100.0
to 100.0
Description: These
parameters allow you to choose the range of data values
to be color mapped in your plot (units are in centimeters). Any data
outside of the range you choose are clipped to the minimum/maximum
values of the color scale. If contouring is selected, contours are
plotted on full range of the data independent of the range of data
values selected.
File Orientation:
Valid Input: Portrait,
Landscape
Description: Here
you can choose the orientation of the plot on the page.
One orientation may provide a larger plot over the other.
File Format:
Valid Input: PostScript,
GIF
Description: Choose
the type of graphics format you wish to receive.
