AITscan™ Launches AreaScanIR Resource

AreaScanIR™, the long-time service of Stockton Infrared’s AITscan™ division has been redesigned to offer archived wide-area infrared and visual imagery to the general public. AreaScanIR’s web site ( has been redesigned and subdivided into three services.  Stockton Infrared Thermographic Services, Inc. (SITS) was founded in 1989 by Gregory R. Stockton and has grown to become an industry leader and innovator of infrared applications.

AreaScanIR™ services offer large mosaic infrared and visual imagery mostly used by clients to know the condition of flat and low-slope roofs. AITscan™ thermographers have flown over, or can fly over large areas of cities with high concentrations of commercial roofs. The three services available from AreaScanIR™ are AreaScanIR™ Professional,  AreaScanIR™ Direct, and AreaScanIR™ Premium, explained below.

AreaScanIR™ Professional – For roof consultants, roofers and roofing manufacturers, AreaScanIR™ Professional can be a valuable sales tool. Cold-calling roof owners to allow their roofing professionals a chance to evaluate a roof can be a tough proposition.  But, by using AreaScanIR™ wide-area archived imagery, roofing professionals will be able to know the condition of a given roof with respect to subsurface moisture contamination, making the sales process more targeted.

AreaScanIR™ Direct – For building owners, building managers, property managers, real estate professionals and insurance company underwriters and claims adjusters, AreaScanIR Direct offers the chance to buy just one building or group of buildings that are contained in the AreaScanIR™ archives. AreaScanIR™ Direct delivers contractor pricing directly to anyone interested in a roof in the archives.

AreaScanIR™ Premium – This service is for any entity interested in the roof moisture condition of multiple roofs over a given geographical area. This is not archived imagery, but new imagery that is flown and then post-processed in a stepped approach. This imagery is the highest resolution available. In the first phase, areas or specific sets of building roofs are selected and flown and then partially post-processed to show the status of the individual roofs. In the second phase, building roofs with problems only are completely analyzed saving the buyer from the expense of post-processing dry roofs.

“We have been collecting infrared and visual imagery for years. AreaScanIR™ provides clients the opportunity to purchase imagery that we have archived,” states Greg Stockton, founder and President of SITS.  “The new website makes the purchase process simple and concise, outlines the potential uses, and lists the geographical areas which imagery as already been obtained.” he concludes.

The US Army Corps of Engineers detonated explosives at the Birds Point levee near Wyatt, Missouri, at 10:02 p.m. on May 2, 2011. Water from the intentional breach flooded a 130,000-acre stretch of land. Two more breaches were detonated on May 3 and 5. This image from the Advanced Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA’s Terra spacecraft shows the resultant flooding of farmland west of the Mississippi 20 miles (32 kilometers) south of the levee breach. On the image, vegetation is displayed in red, bare fields in gray and water in blue. The image covers an area of 30.7 by 39 miles (49.5 by 63 kilometers), and is located near 36.5 degrees north latitude, 89.4 degrees west longitude.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet, or about 15 to 90 meters, ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan’s Ministry of Economy, Trade and Industry. A joint US/Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and, measuring surface heat balance.

A Lovely Swirl: Orbiter Spots a Shifting Vortex at Venus’s South Pole

By John Matson

Venus is Earth’s closest sibling, in terms of size and proximity, but it remains relatively little explored compared with Earth’s other planetary neighbor, Mars. For instance, NASA and the European Space Agency (ESA) currently have three working Mars orbiters and one active Mars rover between them, whereas at Venus, ESA’s Venus Express spacecraft has the place to itself.

Given how little is known about Venus, the exclusive access Venus Express currently enjoys offers plenty of room to make new discoveries about how the planet works. One new such wrinkle in the Venusian sphere is the finding that Venus’s swirling cloud cover, which obscures the planet’s surface from view in optical light, has a shape-shifting, rapidly migrating vortex over the south pole. A team of scientists from Portugal, Italy, France and the U.K., drawing on observations made by Venus Express, announced the finding in a study published online April 7 in Science.

Venus rotates exceedingly slowly on its axis (and in the opposite direction of the solar system’s other planets)—if you were unlucky enough to live on the scorching surface of the planet, you would experience only about two sunrises and sunsets for every trip around the sun. But its super-rotating atmosphere moves much faster, with clouds zipping along at 60 times the rotational speed of the surface. Explanations for the atmospheric super-rotation have been kicking around since the 1970s, but the source of the phenomenon has not been settled conclusively.

That atmospheric swirling causes vortices at the poles with bright filaments that are visible to infrared eyes such as those of Venus Express’s Visible and Infrared Thermal Imaging Spectrometer. An S-shaped northern polar vortex was discovered in the infrared by NASA’s Pioneer Venus spacecraft in the late 1970s, and Venus Express found a similar-looking feature at the south pole in 2006. But the story got more complex as Venus Express returned to the south polar region time and time again to find the southern vortex had moved or changed shape entirely.

“I think the most striking thing about it is it changes so much from day to day,” says lead study author David Luz, a planetary scientist at the University of Lisbon in Portugal. Venus Express is in a 24-hour polar orbit, so it can take a snapshot of the south pole relatively often but cannot watch gradual changes unfold over timescales of several hours. “When it comes back the next day the feature has changed,” Luz says.

The center of rotation of the vortex is offset from the planet’s south pole by about three degrees of latitude, but it migrates around the pole over the course of several days. “We still haven’t figured out what causes it to move around, but we suspect it is related to what is called the meridional circulation,” Luz says, referring to an atmospheric circulation pattern that moves air at high altitudes from the equator to the poles, where the air sinks for an equatorward return at lower altitudes. “We expect that over the poles it is down-welling like a drain,” Luz says. “If the center of rotation is drifting, then we think it probably means that the point of maximum down-welling is drifting.”

Figuring out why the vortex at the pole moves and changes so quickly might help planetary scientists develop a better understanding of Venus’s extreme atmospheric system. “We would like to know how the meridional circulation relates to the motion of the vortex, how the global circulation is feeding the vortex—that’s the missing link,” Luz says.

For now, Venus Express’s latest finding has at least provided a bit more detail to the somewhat sketchy picture scientists have of our neglected planetary neighbor. “It doesn’t solve the problem of the super-rotation” of Venus’s atmosphere, Luz says. “But it’s a clue.”

How ChevronTexaco saved $5.6 million by employing infrared thermography on roofs

$5.6 million. That is the estimated savings George Horn generated for his employer, ChevronTexaco, by applying infrared thermography technology to the company’s headquarters and research and development facilities.

Several years ago, company executives wanted to replace the roofs on all 14 buildings at the company’s headquarters campus in San Ramon, Calif. Horn, superintendent of operations and maintenance for ChevronTexaco Real Estate Management, argued that the roofs were in satisfactory shape and performing well.

“I was adamant that they didn’t need to be replaced,” he says. “But (company executives) wanted to rush right out and replace the roofs.”

To make his case to insistent executives, Horn asked a contractor that had performed infrared surveys for the company to survey the roofs to determine whether leaks had damaged any roofing system materials. The results?

“Their findings backed up my story,” he says. As a result, the company avoided investing unnecessarily — and heavily — in new roofs.

Other maintenance and engineering managers might not be able to generate such savings for their organizations using infrared technology. Nonetheless, growing experience suggests that infrared technology has become an increasingly powerful tool for troubleshooting a range of problems in facility systems, equipment and components.

Up, Up and Away: An article by Greg Stockton about Aerial Infrared Surveys

The imagery (IR) from aerial infrared thermal surveys of facilities, complexes, campuses, military bases and cities can be used for many purposes. Systems like supply steam and condensate return lines, hot water, lines, chilled water lines, supply water mains, distribution piping, storm water drains and sewer lines can be monitored by looking at surface temperatures/patterns. In the case of district heating systems, the distribution system can be flown rapidly and inexpensively to provide thermal data for asset management planning and predictive maintenance (PdM). As a result of finding and repairing leaks in the steam system, energy usage can be reduced with all the related benefits.
