"Plein Air" painting is defined in dictionary.com as "Of or being a style of painting produced out of doors in natural light."
I've been doing a lot of plein air painting since I retired. It was hard to get the daytime hours to do while I was full time employed. I'm thoroughly enjoying getting out into the light again. Here are two very recent examples of plein air, painterly Pam paintings, both fairly small, both done at Great Falls VA.
