a large landfill stretched alongside the freeway. The instrument in the trunk quickly detects a large plume of methane emanating from the landfill.
A NASA aircraft soon appears overhead carrying a prototype satellite instrument that records high-resolution images of methane that scientists can use to identify gas plumes.
The pilot buzzes the landfill several times to capture images of the invisible gas then the plane departs
The instruments in the Prius and airplane are just two of many elements of the Megacities Carbon Project an international multi-agency pilot initiative to develop
Megacities scientists will also periodically take to the road and to the skies to collect mobile measurements of the local atmosphere to better define individual emissions sources and environmental conditions.

A follow-on version of NASA's Orbiting Carbon Observatory-2 that may ultimately fly on the International Space station is being designed with a city mode that will provide frequent maps of the carbon dioxide emissions of many of the world's largest emitters.

so it's expected that the male birds would be making a significant sacrifice in their flight performance for being attractive--possibly giving up their lives
if the train restricts escape from predators such as tigers and leopards in their natural environment Dr Askew said.
and then filmed the same birds taking off without their trains. The display feathers which naturally moult at the end of the breeding season were cropped to judge the change in take off performance between the two states.
Dr Askew observed the position of each bird's centre of mass their wing motions
and the movement of the train in take off and then calculated the amount of power used by the birds to accelerate
and gain height over the first two wing beats. He found it was essentially the same regardless of the presence or absence of the train.
Intuitively you expect that the train would detrimentally affect flight performance and so not finding a detectable effect was a bit surprising Dr Askew said.
These birds do not seem to be making quite the sacrifices to look attractive we thought they were.
The train of the peacock is one of the most iconic examples of sexual selection in the animal kingdom.
Dr Askew also looked at how much drag the train created during take off by mounting a detached train in a wind tunnel.
Therefore the impact of the train on the overall take off performance is negligible allowing birds with
and without trains to invest the same amount of power in the ascent. The results do not mean that having an ornate train carries no costs for peacocks.
Dr Askew pointed out that the feathers might adversely affect flight stability and the birds'ability to run.
Just creating the ornate plumage is a costly exercise; male birds invest about 3%of their daily metabolic energy budget in train growth.
