SATELLITE REVEALS NEW VIEWS OF PLANET EARTH AT NIGHT
Scientists have unveiled an unprecedented new look at our planet at night. A
global composite image, constructed using cloud-free night images from a
new NASA and National Oceanic and Atmospheric Administration (NOAA)
satellite, shows the glow of natural and human-built phenomena across the
planet in greater detail than ever before.
Many satellites are equipped to look at Earth during the day, when they can
observe our planet fully illuminated by the Sun. With a new sensor onboard
the NASA-NOAA Suomi National Polar-orbiting Partnership (NPP) satellite
launched last year, scientists now can observe Earth’s atmosphere and surface
during nighttime hours.
The new sensor, the day-night band of the Visible Infrared Imaging Radiometer
Suite (VIIRS), is sensitive enough to detect the nocturnal glow produced by
Earth’s atmosphere and the light from a single ship in the sea. Satellites in the
U.S. Defense Meteorological Satellite Program have been making observations
with low-light sensors for 40 years. But the VIIRS day-night band can better
detect and resolve Earth’s night lights, providing researchers with valuable data
for a wide variety of previously unseen or poorly seen events.
“For all the reasons that we need to see Earth during the day, we also need to
see Earth at night,” said Steve Miller, a researcher at NOAA’s Colorado State
University Cooperative Institute for Research in the Atmosphere. “Unlike
humans, the Earth never sleeps.”
The day-night band observed Hurricane Sandy, illuminated by moonlight,
making landfall over New Jersey on the evening of Oct. 29. Night images
showed the widespread power outages that left millions in darkness in the wake
of the storm. With its night view, VIIRS is able to detect a more complete view
of storms and other weather conditions, such as fog, that are difficult to discern
with infrared, or thermal, sensors. Night is also when many types of clouds
begin to form.
“The use of the day-night band by the National Weather Service is growing,”
said Mitch Goldberg, program scientist for NOAA’s Joint Polar Satellite System.
For example, the NOAA Weather Service’s forecast office in Monterey, Calif., is
now using VIIRS day-night band images to improve monitoring and forecasting
of fog and low clouds for high air traffic coastal airports like San Francisco.
According to Goldberg, VIIRS images were used on Nov. 26, the Monday after
Thanksgiving, to map the dense fog in the San Francisco Bay area that resulted
in flight delays and cancellations.
Unlike a camera that captures a picture in one exposure, the day-night band produces an image by repeatedly scanning a scene and resolving it as millions of individual pixels. Then, the day-night band reviews
the amount of light in each pixel. If it is very bright, a low-gain mode prevents the pixel from over-saturating. If the pixel is very dark, the signal is amplified.
“It’s like having three simultaneous low-light cameras operating at once and we pick the best of various cameras, depending on where we’re looking in the scene,” Miller said. The instrument can capture images
on nights with or without moonlight, producing crisp views of Earth’s atmosphere, land and ocean surfaces.
“The night is nowhere as dark as we might think,” Miller added.

NPP satellite in April and October 2012. The image was made possible by the satellite’s “day-night band” of the
Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to
near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires
and reflected moonlight. Credit: NASA Earth Observatory/NOAA NGDC
JUST FOR BEST FRIENDS
OLD DOGS, NEW TRICKS
Innovative Ways to Care for Your Elderly Canine Companion
Ever wonder if there was more you could have done, or could be doing to
keep your older dog healthier and happier in its golden years? Well, I often think
about what I could have done to provide a better quality of life to my beloved girl,
“Lady” when she started showing signs of her age before she passed away 11 years
ago. She was at least 19 or 20 years old at the time, based on her estimated age of
2 when I adopted her from the El Segundo SPCA. Back then I was nowhere near
as informed as I am today about the health and emotional needs of an elderly dog. Although I know for sure she got plenty
of love and tender care, I can’t help thinking of how much more I could have done to keep her comfortable as her final day
approached.
Now that my current dog “Tater” is moving into the senior stage of her life, I am so pleased to have the many information
resources made available by the internet and by my veterinarian, Dr. Sylvia Domotor, who has gained a wealth of knowledge
about caring for elderly dogs over the many years she‘s been in practice. Dr. Domotor’s wise advice to owners of senior dogs
is to recognize that they are indeed old and are unable to do many of the things they were able to do when they were young. It
is really no different from what happens when we humans get old. “Patience is number one” she said in a recent conversation
regarding caring for older canines. “Sometimes we forget how old they are. Dogs are considered seniors at 7 and that is when
they begin to lose their hearing, their eyesight and their olfactory senses. Understanding why an elderly pet might poop or pee
in inappropriate places, or fail to respond to a recall is very important in having patience with them.”
Although manufacturers do tend to exploit the ever-growing market for elderly pet care products, statistics indicate that dogs
are living longer these days, presumably due to improved technology in veterinary care and the development of innovative
products to help accommodate the specials needs of our furry senior friends, and keep them more comfortable. Specially
formulated kibble, therapeutic beds, specialized food bowl designs, ramps to help “Fido” get up into the car, restraining
harnesses for the ride, diapers for incontinence, dietary supplements, herbs and holistic remedies designed to cosset a senior
dog through its last years are among the many new products found on the shelves of most pet supply stores today. Doting
pet owners find it hard to resist blowing the bundle to help their four-legged family member, and I am most definitely one of
them. I can’t count how many times I have walked out of the store or vet‘s office thinking, “There goes this week’s dog-walking
profits! I guess the money just goes from one dog to another, but she’s worth it!”
Besides the many products now available to help keep a senior pet comfortable and as healthy as possible, spending quality
time with an older dog is extremely important for their mental and physical health. I have recently noticed that my girl Tater,
who will be 11 years old in March, has become more demanding of my attention than ever before; I attribute most of that
neediness to her age. Her favorite time of day is when I come home after walking several dogs, and lay up on the couch where
she insists on joining me for an afternoon nap. I always let her lay with me, even though she is quite enormous and takes up
all the space, because I can tell she needs that time with me. She lets out a low groan, and lays her huge head on my shoulder
where she falls asleep and snores right into my ear. I am not looking forward to the day when she can’t get herself up on the
couch, but when that happens I guess I’ll have to get her a specialized stair step that will allow her to climb up where she knows
she’ll get a fine ration of hugs and loving!
I find it amazing how human’s priorities change when it comes to caring for an elderly dog. I was truly touched when I
heard that singer Fiona Apple had cancelled the South American leg of her tour last month, so she could fly back home and
stay with her ailing 14-year old pit bull “Janet”. Considering how much money she must have forfeited to make that choice,
not to mention disappointing thousands of ticket holders, that says a lot about how much Fiona Apple loves her dog. In
one part of a heart-warming apology letter to her fans, Apple
wrote: “I know she is coming close to the time where she will
stop being a dog, and start instead to be part of everything.
She’ll be in the wind, and in the soil, and the snow, and in me,
wherever I go. I just can’t leave her now, please understand.
If I go away again, I’m afraid she’ll die and I won’t have the
honor of singing her to sleep, of escorting her out. . .”
As dog lovers, I think we can all relate to what Fiona Apple
is going through, and understand why she made it a priority
to spend quality time with her beloved old girl, Janet versus
continuing her tour. I can’t think of anything that could keep
me away from Tater when her time is close in coming. They
give us so much unconditional love, and nothing - including
money or fame can possibly compare to that.
