The North Polar Region of Mars in 2016

This paper describes observations of Mars' North Polar Region. The remnant North Polar Cap has extended to a mean latitude near 82° N throughout most of the 20th and early 21st centuries. Deposited dust, however, may affect the perceived size of this cap. In 2016, clouds were scarce in the North Polar Region until late summer. On March 10-11, 2016 an annular cloud was imaged near 100° W, 65° N. Examples of similar clouds imaged in previous years are summarized.
