As originally proposed, Junocam was to be a copy of the MSL MARDI instrument with additional radiation shielding and a «pushframe» color filter array in place of the «Bayer pattern» filters of MARDI.

The water around the reactor core serves as three things: a neutron moderator, meaning it slows down the fast neutrons released during fission, which then sustain the chain reaction; a cooling agent; and a radiation shield.

The ozone layer helps shield life on the planet from potentially harmful ultraviolet radiation that can cause skin cancer, cataracts, and suppress immune systems, as well as damage plant life.

Earth's magnetic field shields us from deadly cosmic radiation, and without it, life as we know it could not exist here.

As volcanic ash shields the Earth from solar radiation, unusually cool temperatures rose, leading to famines and plagues.

Factors such as the sizes of the planet and the star, continental distribution, ocean depth, the amount of water present, tectonic activity, variability of the surface temperature, atmospheric composition, the magnetic shield, speed of rotation, axial tilt, eccentricity of the orbit, the type and amount of radiation received, the age of the solar system, and the possibility of panspermia within the system are all considered.

Early Earth lacked an ozone layer to act as a shield against high - energy solar radiation, but microbes flourished by adapting to or finding other forms of protection from the higher ultraviolet radiation levels.

The surface of Mars today — as seen from the myriad of robotic space missions sent to explore our next - door neighbor — appears cold and desert - like, and its whisper - thin atmosphere doesn't shield the planet from a bombardment of radiation from the Sun.

They also shield as much normal tissue as possible while they aim the radiation at the site of the cancer.

Using a number of approaches, the normal tissue that surrounds the tumor is «shielded» from this beam so as to limit the side - effects associated with radiation.

Lunar lava tubes have been discovered [5] and have been studied as possible human habitats, providing natural shielding from radiation.

The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.

I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).

The moon, for example, is much cooler than the Earth, but as you noted, it radiates energy because it's temperature is above zero K. Certainly you are not suggesting that the Earth has some «smart shield» around it that redirects the radiation from the moon, but lets the sun's radiation in.

Make this capsule in the same manner as dewar flasks — that is a vacuum layer between all the radiation shields; and,

The Earth's temperature has warmed in the modern era as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (as illustrated here by Ogurtsov et al., 2012 and detailed by Avakyan, 2013, McLean, 2014, and others).

He theorizes that the Earth's temperature has warmed in the modern era as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (as illustrated here by Ogurtsov et al., 2012 and detailed by Avakyan, 2013, McLean, 2014, and others).

The ozone layer acts as a shield for the planet that prevents dangerous radiation from reaching the biosphere, where humans, plants, and animals reside.

This is also consistent with the bonchardi mechanism mode, which fairly consistently indicates we can expect a reversal of ambient air temperature increase with the next day, as the dual modality of reverse recapture recombination functions as an equalizer, and the increase in low level re radiation acts as a «heat shield» keeping more air from reaching and warming the ground, allowing ice to reformulate, while most of the temporary heat, which will largely be offset by the Atlantic shift paradigm anyway, given the lower absolute percentage of (so called?)

As you are above the low altitude clouds and a good deal of the atmosphere there, I'd expect incoming solar radiation (however the sensor is shielded) and reflected short wave from lower clouds to cause a warm bias if anything.

There are also metal (thermal) radiation shields sitting intermediately between the inner very cold area and the outside which limit the heat flow from the outside, much as greenhouse gases in the atmosphere, limit the rate at which the surface cools.
