Section 4: Land Based Radar Data

The Data Center has obtained radar data from several different sources:
15 NWS sites, the Geophysics Lab (AFSC) at Hanscom AFB, and the Halifax
and Holyrood radars. Airborne radar data from the WP-3Ds are covered in
section 2 (see sections 2.1.3 and 2.1.4)

Radar data from several other Canadian stations can be obtained from
the AES, contact Dr. Norman Donaldson for more information.

4.1	Canadian Radar Data

4.1.1	Halifax and Holyrood Digital Radar Data	

Form:		digital		
Size:	
Volume:		5 tapes from each site

This digital radar data contains 10-minute volume-scans of 5 cm data to
about 200 km from Halifax and Holyrood (near St. John's, Newfoundland). The
Holyrood radar is a Raytheon C-band radar and is part of the AES national
network. The radars were located at:

	Halifax, NS (YHZ)	44.87N	63.50W
	Holyrood, NF	47.70N	53.20W

A sample program to read these data was provided by Norman
Donaldson of AES. Printed CAPPIs of these data are also available (see
section 4.1.2 below).

4.1.2	Halifax and Holyrood Radar CAPPIs	

Form:	paper.	
Size:	8.5"x11"	
Volume:	175 pages total	

1.5 km radar CAPPIs (Constant Altitude Plan Position Indicators) are provided
for every hour during IOPs. The CAPPIs are black and white, with six CAPPIs on one
8 x 11 page. There are 68 pages for Holyrood and 107 pages for Halifax. These data
were derived from the digital data described above (see section 4.1.1).

4.2	U.S. Radar Data

4.2.1	NWS Radar Scope Photographs on Microfilm.	

Form:		microfilm, paper	
Size:		8.5S x 11S (paper)
Volume:		117 rolls of microfilm	

The EDC has obtained copies of the scope films for the 15 NWS radar sites
listed below for the ERICA period. Copies of these films can be obtained from NCDC.
The Data Center will loan the films to interested researchers, or generate select
hardcopy on request.

	Station	Location	Latitude (N)	Longitude (W)	# of films
	ACY	Atlantic City, NJ	39.45	74.57	8
	AHN	Athens, GA	33.95	83.32	10
	AQQ	Appalachicola, FL	29.72	85.03	7
	AYS	Waycross, GA	31.27	82.40	7
	CHS	Charleston, SC	32.90	80.03	7
	CRW	Charleston, WV	38.39	81.61	6
	DAB	Daytona Beach, FL	29.18	81.05	8
	HAT	Cape Hatteras, NC	35.27	75.55	7
	ILM	Wilmington, NC	34.27	77.92	8
	JKL	Jackson, KY	37.59	83.32	7
	NHK	Patuxent River, MD	38.29	76.42	10
	PIT	Pittsburgh, PA	40.53	80.22	9
	TBW	Tampa Bay, FL	27.70	82.40	7

4.2.2	NWS Radar Summary Charts

Form:		paper, microfilm
Size:		8.5Sx11S
Volume:		3 rolls of microfilm

NCDC routinely creates a microfilm archive of NMC hourly radar summary
charts. These charts show an hourly radar summary for the entire U.S. Each of three
microfilms contains one month of charts, with one chart per hour. Selected hardcopy
can be generated at the EDC.

4.2.4	Hanscom AFB Color Scope Photographs

Form:	photographic prints
Size:	8.5S x 11S
Volume:	55 photos total		

These photos show the AFGL low-level reflectivity displays (PPIs) at
approximately hourly intervals. There are 21 photos for IOP 3 (18-19
Jan.) and 34 photos for IOP 8 (23-25 Feb.) They were provided to the
EDC by James Metcalf of the Geophysics Laboratory (AFSC) at Hanscom
AFB in Mass. The radar is located at 42.41N, 71.49W. The photos are
available as a loan from the Data Center.  Researchers interested in
obtaining digital data from the AFGL radar site should contact Dr.
James Metcalf.
