A subsidiary page of The Radar Entomology Web Site.

Displays of insect echo from entomological and meteorological radars. An index to radar images placed on line by a variety of researchers.

Displays from entomological radars:-

 Images from a scanning radar (Texas) Images of insect tracks, insect alignment and layering, and an insect cloud. (From APMRU.)

 PPI images of long-distance migration of insects - probably mainly cotton bollworm (Heliothis armigera) moths - near Beijing, China, observed with the CAAS Entomological Radar.

 Bumble-bee flight observed with a harmonic radar. (Courtesy of IACR/NRIRU.)

 Honeybee drone flight (in a "drone congregation area") (Arizona, USA). An annotated image from CHBRC.

Displays from meteorological radars:-

It is known that many of the following links are broken. The page will be edited in due course. Apologies.

 Insects and ground clutter (Florida, USA). An annotated image from the MIT Radar Lab.

 Insects in the boundary layer above a boreal forest (Manitoba, Canada). An image from NOAA's Environmental Technology Laboratory.

 "Clear-air return" (radar echo) from insects near Kansas City (Missouri, USA). An image from the University of North Dakota's Doppler weather radar. (Courtesy Ronald Rinehart.)

 Spring migration of day-flying insects (and night-flying birds) into Canada on a strong southerly wind. An annotated image from "Radar Meteorology at McGill" (McGill University, Montreal, Canada). See also the TREWS Questions and Answers page for some related discussion. An image of insects in daytime convection from the Department of Atmospheric and Oceanic Sciences's Vertical Pointing Radar also appears on this site. The VPR has many similarities with the vertical-beam radars used by radar entomologists - APMRU's VLR, NRIRU's VLR, and ASoP's IMR.

 Insects (identification tentative) migrating ahead of a southerly surge, Monterey Bay (California, USA). An image from NOAA/National Weather Service Western Region Headquarters.

 Day-flying insects (identification tentative) observed by weather radar at Carvel, near Edmonton, Alberta. Images (numerous)* and animations* from Environment Canada's King Weather Radar Research Station. See also the TREWS Questions and Answers page for a discussion of these images.
*Links broken - sorry; paragraph under review and may be removed.]

 Insects seen with a vertical-looking FM/CW radar (New Mexico, USA). (From the U.S. Army Research Laboratory at White Sands Missile Range, New Mexico, U.S.A.; image located on APMRU's Entomological Radar Studies pages.)

 Insect observations with the Tuulia meteorological radar (Department of Meteorology of the University of Helsinki) near Helsinki, Finland. A series of pages covering: mass migrations of aphids into Finland in 1988; aphids in a sea breeze front; a vertical-section display of insects (unidentified) in another sea breeze; a PPI image showing insects exhibiting a common orientation direction; Doppler spectra of radar echo from insects; and an account of an invasion of moths (apparently Diamondback Moths Plutella xylostella) into southern Finland which includes radar-based estimates of the number of immigrants.

 Insects and bats seen with a Doppler weather radar (Texas, USA). Video, look for 'Doppler radar' link in 'Multimedia' box at right. From National Geographic (McCracken & Westbrook 2002).
