June 22, 2006
On June 22, a frontal boundary drifted slowly south across Oklahoma, with scattered showers and thunderstorms across the region. A number of small, isolated and nearly stationary storm cells can be observed across IP1, with some Mesonet sites receiving over 1.3" of rain.
Data were collected at the Rush Springs (KRSP) and Lawton (KLWE) radar sites at 1.0 and 3.0 degree elevations. Note that at this stage of testing, the radars were not yet operating in DCAS mode (instead scanning 360 degrees), and some technical problems remained (e.g., ground clutter, missing radials).
August 3, 2006
A cold front crossed the state on August 3rd, with scattered convection across
the IP1 network. Rain totals of up to 0.80 inches were recorded by Mesonet sites within IP1.
Data were collected at the Chickasha (KSAO) and Rush Springs (KRSP) sites at 3.0 and 4.0 degree elevations. NEXRAD data from KTLX and KFDR are available.
Select IP1 and NEXRAD images also are available.
August 15, 2006
An east-west oriented frontal boundary stalled across the state and provided a focus region for convective development. On the afternoon of August 15, isolated strong to severe thunderstorms developed from 2100 UTC to 0100 UTC (August 16).
A second area of stratiform precipitation with embedded convection developed across IP1 from 0100 UTC to 0500 UTC.
Data were collected from the IP1 radars at Cyril (KCYR), Chickasha (KSAO), and Rush Springs (KRSP) at 0.0, 1.0, 3.0, 4.0, 6.0, 8.0, and 10.0 degree elevations.
Merged IP1 images and KFDR data and images are also available.
August 22, 2006
A stalled frontal boundary across IP1 led to over one inch of rain between approximately 1000 UTC and 1400 UTC on August 22nd.
Data were collected at the Chickasha (KSAO) and Rush Springs (KRSP) IP1 sites at 3.0 and 4.0 degree elevations. NEXRAD data at KTLX and KFDR are also available.
September 21, 2006
A low pressure system in KS with a trailing cold front moved slowly west to east across IP1 from approximately 0600 UTC to 1500 UTC. The front brought with it a mix of light to moderate showers and thunderstorms. Although Mesonet sites recorded only 0.25" of rain, some areas likely received much more.
Data were collected at the Cyril (KCYR), Chickasha (KSAO) and Rush Springs (KRSP) IP1 sites. The radars were operated in DCAS mode at 3.0 and 4.0 deg elevations, and several good examples of DCAS can be found in the KCYR data. Merged radar data are also available for this case.
November 5, 2006
A warm front moved from south to north across the state on Sunday, November 5th, and brought with it scattered showers and thunderstorms. Up to 0.75" of rain fell across portions of the IP1 testbed. Data were collected at the Cyril (KCYR), Rush Springs (KRSP), and Lawton (KLWE) IP1 sites at 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, and 10.0 degree elevations. Multiple radar data (MULTI) are available, and NEXRAD data from KFDR is available.
November 27 - 28, 2006
A stalled front across NW Oklahoma led to scattered showers and thunderstorms across portions of the state. Up to 0.25" of rain fell across portions of the IP1 testbed. Data were collected at the Cyril (KCYR) and Rush Springs (KRSP) IP1 sites at 1.0 and 3.0 degree elevations. Multiple radar data (MULTI) are also available.
November 29 - December 1, 2006
A strong artic cold front moved from NW to SE across Oklahoma 11/29-11/30, with significant overrunning precip along and behind the front. Up to 3-5" of sleet and snow fell across portions of the IP1 testbed. Data were collected at the Cyril (KCYR) and Rush Springs (KRSP) sites. Full 360 degree scans were collected at 1.0 and 3.0 degree elevations with sector scans including 5.0, 7.0, 9.0, and 11.0 degree scanning. Multiple radar data (MULTI) are also available.
