Standing in the sun is more pleasent on a cold winter day than standing in shade. Is the temperature of air considerably higher than that of air in the shade?

Radient heat is considerably more. Air does not transfer heat well.

In the sun, you are getting direct heat on skin (direct energy absorption) which gets transferred into blood which raises the body temperature --a good thing.
In shade the body temp will not rise becuase sun-light is not being absorbed. Instead body must burn food to raise its temerature.
The air temperature in shade will be only slightly lower.

The temp of the air is not what makes you warm. The air takes away the heat in both situations. The sun warms your skin or your clothing, which can make you more comforatable than being in the shade with no source of heat outside of the burning of the fuel within your body.

the shade has a considerably lower temperature despite that fact that is is open to the outside where there is no shade, reason is air doesn't heat up as much as the ground, therefore when you stand in the shade its much more cooler than if you were outside

yes , the air not in the shade gets it heat from the elements around it, ie:pavement, soil, rocks,buildings etc and the heat from these rise up and make the air in that area hotter, then if you were under a tree.
You should always take the outside temperature in the shade, and about 3ft off the ground to make a accurate reading.

No, you're just absorbing a lot more radiant heat in the sun than in the shade. If you try to measure this with a thermometer, note that a thermometer in the sun isn't measuring the air temperature, it's measuring the thermometer temperature, and the thermometer is absorbing radiant heat from the sunlight!

Yes the air in the shade is only mildly cooler, because air still circulates under it. Mostly standing in the shade cuts out UV and other harmful radiation from reaching your body.

However good your calculation, a simple thing like hard water can hit your coefficient for a six. In any case , you cannot increase the overall coeff by calculation and any number of iterations. If you ask me, i will suggest that you stick to the lower end of reported values, which will give some insurance. Organic vapours are tricky in that if any high boiling components are present they can form a fouling film quickly dropping the coefficient far below the designed values. You may mail me through my profile if you want a more detailed discussion.

No, its the radiant energy from the sun that warms you, although the air may be just as cold in the sunlight.

No, its not. The sunlight that hits your body transfers heat through your body but the air temperature stays relativley constant. Its the sunlight that heats you up

light rays travel and other rays travel from the sun
to us here on earth no i have to say no
at the same time how hot the rays are could warm the air in the sun a little more so
my answer yes and no thank you
