Case Studies

 January 12-13, 2007
A strong cold front led to an extreme sleet/freezing rain event. Data were collected at KRSP and KLWE at 1.0 and 3.0 degree elevations.  

 February 12, 2007
A low pressure system moved east across Oklahoma leading to scattered showers and thunderstorms across southern portions of the state, including a strong squall line which moved directly through the network. Data were collected at all four IP1 sites (KRSP, KLWE, KCYR, and KSAO) at 1.0 and 3.0 degree elevations. Data were also collected at 0.0 deg at KLWE and KRSP, and at 4.0 and 5.0 degrees at KSAO. Multiple radar data (MULTI) are also available.  

 Feb 12 (Tier2a)

 February 24, 2007
A cold front and dryline led to scattered thunderstorms across IP1 from 0530-0930 UTC. Data were collected at all four IP1 sites (KRSP, KLWE, KCYR, and KSAO) at 1.0 and 3.0 degree elevations. Multiple radar data (MULTI) are also available. For this case, most data were collected in non-DCAS mode.  

 March 10-11, 2007
A stationary front and developing low pressure system in TX allowed for a heavy rain event to develop across the network. Over 2 inches of rain fell in some locations during March 10-12. Data were collected at all four IP1 sites (KRSP, KLWE, KCYR, and KSAO). Simple 360deg PPIs were collected at 2.0 degrees elevation during a heavy rain episode from 07UTC to 17UTC. The event was primarily stratiform with embedded convection. Merged radar data (MULTI) are also available.  

 March 11-12, 2007
During the evening of March 11, a 2nd round of showers and thunderstorms crossed IP1 between 21UTC and 03UTC. Data were collected at all four IP1 sites (KRSP, KLWE, KCYR, and KSAO) in DCAS mode using a 60-sec heartbeat. Complete 360deg PPIs were collected at 2.0deg, and sector scans were collected at 1.0, 3.0, 5.0, 7.0, 9.0, and 11.0 degree elevations. Merged radar data (MULTI) are also available.  

 April 10, 2007
A small area of severe thunderstorms developed across IP1 the evening of April 10 from approximately 22-02 UTC. Several thunderstorm and tornado warnings were issued; severe hail and winds were observed within the test bed. Data were collected at all four IP1 sites in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, 14, 17, 22, and 27deg. Merged radar data (MULTI) are available.

 April 10 (Tier2a)

 April 24, 2007 (a.m.)
Early morning elevated, non-severe convection occurred on the morning of April 24 from 14-16 UTC. Several isolated cells developed just south and west of IP1, and moved NE directly through the center of the test bed. Data were collected at all four IP1 sites in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, and 14 deg.  

 April 24, 2007 (p.m.)
A Tornado Watch was issued in anticipation of a significant severe wx outbreak. Instead, a severe squall line developed just west of IP1, and moved through the test bed from 17-20UTC. Large hail was prevalent along the line. Data were collected at three sites (KSAO, KCYR, and KLWE) in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, and 14 deg.

 May 8, 2007 (Tier2b)
A large area of convection with embedded supercells moved north from TX into the testbed. Several areas of significant circulation were detected from KLWE and KCYR between 00UTC and 03UTC (May 9). Potential tornado touchdowns are possible, within the Ft. Sill military reservation and points north. Data were collected with all 4 radars in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0 deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, and 14 deg.

A strong cold front pushed across OK from north to south. Data were collected with 2 radars (KLWE and KRSP) in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0 deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, and 14 deg.

A low pressure center in SW KS with a trailing dryline/cold front. Data were collected with 2 radars (KLWE and KCYR) in DCAS mode using the 20+40-sec heartbeat. Complete 360deg scans were collected at 2.0 deg, and sector scans were collected at 1, 3, 5, 7, 9, 11, and 14 deg.
