WISP94 CP4 Data Availability
About These Data
NCAR's CP4 radar operated in support of the Winter Icing and Storms
Project during February and March 1994. For project weather
summaries, please click here
RDP maintains a permanent archive of all CP4 data for this project,
and may be contacted for data requests. For information on ordering

GoTo Introduction, WISP94 CP4 Operations Report
Tapes and Time Periods Available
The following tape data with the indicated time spans are available.
Note that time gaps may occasionally exist within a tape, and the
summary information file should be consulted to determine if a
specific time period actually exists on tape (click on the tape
number to view the summary file; click here for general
information about the contents of the summary files). Tape numbers
shown are RDP archive numbers, and may be referenced when requesting
data. Click on the 
button
(when present) to review radar scan patterns for the time period of a
corresponding tape.
Movie loops of low-level scans have been created for some tapes during
certain radar projects. If a movie exists, you will see the 
icon on the line with the tape number.
Click on this icon to get a
good summary of radar data for the period of the data tape. Note that
these movies may be long! (2 to 4 Mbytes is not unusual). Also note
that a given movie may actually extend into the time period of the
next tape in the list; no icon will then appear for this next tape (if
you think you want to view a movie for a given tape, but the icon is
not present, try using the loop for the preceding tape).
Movies can be provided on tape media for users who desire their
own copy, or in cases where lack of sufficient network bandwidth makes
access a torment.
For WISP94, images are compiled from .5 degree surveillance
scans at 10 minute intervals. The images have been processed into
movies using MPEG routines. Note that there is some loss of detail
during this processing, and on occasion, artifacts have been
introduced by the MPEG routines. Additionally, note that the times
shown on the images are not necessarily accurate (in some cases, they
are off by about 10 minutes), and that there are frequently scan
glitches near 90 degrees azimuth; both of these problems are
associated with shortcuts taken to prepare the data for on-line
access, and should not be interpreted as reflecting real problems with
the archived dataset.
For some of the WISP94 movie loops, the location of Boulder,
Stapleton International Airport, and Downtown Denver are shown by the
letters B, S, and D, respectively.
These images are meant to serve as a quick overview of radar data
collected during a field project. The images represent degraded data
that are not suitable for quantitative analysis! Full resolution
radar data and the software required to process these data are
available from the National Center for Atmospheric Research, Research
Data Program of the Atmospheric Technology Division. Again, for
