| ==CSU-CHILL== | | ==Weather Radars== |
| CSU-CHILL is a transportable dual-polarization radar system, with a 9 meter parabolic dual-offset reflector antenna. The radar features two S-band [[CHILL Transmitters|dual Klystron transmitters]] driving each polarization channel, and an X-band transmitter driving the two polarization channels. Each S-band transmitter develops approximately 1 MW of power, while the X-bands generate 25 kW. The transmitters are controlled by a flexible digital waveform generator, which can synthesize a wide variety of polarization states. The [[CHILL Receivers|low-noise receivers]] are connected to a [[CHILL Signal Processor|customized signal processing system]], which can output various polarimetric moments. Moment data, as well as raw time series data can be archived for later study. The facility is connected to the CSU network through a [[Wireless Link|high bandwidth microwave link]], which provides up to 30 MBps data rate. | | ===CSU-CHILL=== |
| | [[CSU-CHILL S- and X-band]] is a dual-wavelength S- and X-band, dual polarization scanning radar system located at the [[CSU-CHILL main site]]. The S-band transmitter can be selected between dual 1 MW Klystron transmitters or solid-state 24 kW transmitters. The X-band transmitter is a 25 kW magnetron. The antenna is an 8.5m dual-offset (1° at S-band, 0.3° at X-band). |

| ===Requesting Use of the Facility=== | | ===FrontX=== |
| Projects conducted at the facility can be classified into
| | [[FrontX]] is an X-band phased array radar system developed in partnership with FirstRF corp. It features a single-axis electronic scan antenna mounted to a mechanical positioner system, and is trailer-mounted. The combined transmitter power from the 64 T/R modules is 70W, and has a 2° beamwidth. |
| ====Major Projects====
| |
| These projects usually involve moving the radar, larger time scales of observation (typically in excess of 20 hours) and requires the involvement and funding from the National Science Foundation (NSF). Please [[Contacts|contact the Scientific Director]] for details on requesting the use of the facility.
| |
|
| |
|
| ====Cost-recovery==== | | ===CSU Pawnee=== |
| These are larger projects that do not involve funding from the National Science Foundation. A daily use fee will be charged during the data collection process. Please [[Contacts|contact the Scientific Director]] for details on requesting the use of the facility.
| | [[CSU Pawnee S-band]] was a single-polarization S-band radar, and was decommissioned in 2015. |
|
| |
|
| ====20-hour Projects==== | | ==Locations== |
| 20 hour projects were conceived as a method to provide simplified access to the radar for users with specific data collection requirements that can be supported with modest facility effort, typically, no more than ~20 hours of radar operational time. 20 hour project investigators (and often their students) also gain valuable experience in the overall planning and conduct of meteorological field research activities.
| | CSU-CHILL currently administers two permanent sites in Colorado |
| | * [[CSU-CHILL main site]], Greeley CO |
| | * [[ARDEC South radar site]], Fort Collins CO |
|
| |
|
| 20 hour projects have secondary priority to the support of NSF-allocated research projects. Their support is also contingent upon scheduled radar maintenance/upgrade activities and facility staff availability. 20 hour project expenses are currently provided by the facility’s NSF base funding.
| | ==Lab Facilities== |
| | | In addition to the radar and remote sensing equipment, the CSU-CHILL facility also hosts an [[RF Instrument Lab]], which is used by both CHILL staff as well as CSU students during construction and maintenance of the radar equipment. |
| To request a 20-hour project, please Fill out the [https://docs.google.com/a/rams.colostate.edu/spreadsheet/embeddedform?formkey=dEN2ODlYaE1HenYzdHFyMDZLNGw2M2c6MQ Small project application form].

| ===Technical Documentation=== | |
| Technical details of the CHILL radar are described in the {{pdf|brochure_web.pdf|CSU-CHILL Technical Brochure}}. A more detailed description of the hardware and software architecture of CHILL is given in the [[hardware description]].
| |
| | |
| ==CSU-Pawnee==
| |
| The CSU-Pawnee Doppler radar was a single-polarization S-band radar system, with a Klystron transmitter. It was decomissioned in March 2015. It was located 48 km NNW of the CSU-CHILL radar. The radar system was used in a dual-doppler configuration along with CSU-CHILL, and performed synchronized scans.
| |
| | |
| [[Image:Pawnee Radar.jpg|center|300px|thumb|CSU-Pawnee Radar]] | |
| | |
| The radar transmitter frequency was 2.730 GHz, and used a vertically polarized antenna with a 1.6° beamwidth. The signal processor used was the same as that used in CHILL. The transmitter generated an output power of 425 kW. The radar was located at latitude <nowiki>40° 52.269' (N 40.87115) and longitude 104° 42.84' (W 104.714) </nowiki>, at an altitude of 1688 m MSL.
| |
| | |
| Some [[:Category:CHILL_PAW_dual_Doppler|example cases]] of dual-doppler data collected with the CHILL-Pawnee dual-doppler network are available on this website.
| |
| | |
| ==FRONT==
| |
| The Front Range Observational Network Testbed (FRONT) is anchored by the CSU-CHILL and NCAR S-Pol NSF research radars. Very cost effective data collection can be done while these radars are at their home base locations (Greeley and Firestone CO respectively.) In conjunction with the neighboring NWS WSR-88D radars at Cheyenne, WY and Denver, CO, dual-polarization / multiple-Doppler radar coverage is available over a wide region that includes a variety of terrain complexity.
