Water Ice Clouds in the Martian Atmosphere: General Circulation Model Experiments with a Simple Cloud Scheme Mark I
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 107, NO. E9, 5064, doi:10.1029/2001JE001804, 2002 Water ice clouds in the Martian atmosphere: General circulation model experiments with a simple cloud scheme Mark I. Richardson Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California, USA R. John Wilson Geophysical Fluid Dynamics Laboratory, National Oceanic and Atmospheric Administration, Princeton, New Jersey, USA Alexander V. Rodin Space Research Institute, Planetary Physics Division, Moscow, Russia Received 17 October 2001; revised 31 March 2002; accepted 5 June 2002; published 20 September 2002. [1] We present the first comprehensive general circulation model study of water ice condensation and cloud formation in the Martian atmosphere. We focus on the effects of condensation in limiting the vertical distribution and transport of water and on the importance of condensation for the generation of the observed Martian water cycle. We do not treat cloud ice radiative effects, ice sedimentation rates are prescribed, and we do not treat interactions between dust and cloud ice. The model generates cloud in a manner consistent with earlier one-dimensional (1-D) model results, typically evolving a uniform (constant mass mixing ratio) vertical distribution of vapor, which is capped by cloud at the level where the condensation point temperature is reached. Because of this vertical distribution of water, the Martian atmosphere is generally very far from fully saturated, in contrast to suggestions based upon interpretation of Viking data. This discrepancy results from inaccurate representation of the diurnal cycle of air temperatures in the Viking Infrared Thermal Mapper (IRTM) data. In fact, the model suggests that only the northern polar atmosphere in summer is consistently near its column-integrated holding capacity. -

June Solstice Activities (PDF)
Arctic Connection Linking Your Place to the MOSAiC Expedition June Solstice Edition Introduction As I write this, it is the June Solstice. The exact moment of solstice occurred a few hours ago, at 21:44 Universal Daylight Time. This was at 1:44 pm today here in Homer, Alaska. This moment marked when Earth’s north pole leaned most toward the sun, and the Earth’s south pole was tilted most away from the sun. On this day, the sun appears directly overhead at local noon for those living at 23.5 degrees north (the Tropic of Cancer), as far north as the sun ever gets. And during the December solstice, the sun appears directly overhead for those living at 23.5 degrees south (the Tropic of Capricorn). (In case you need a refresher, here’s the basic science from Earth & Sky.) In the northern hemisphere, the June Solstice is called the summer solstice and represents the day(s) with the most amount of daylight. I say days because in some parts of the northern hemisphere, the sun has stayed above the horizon for multiple days now and won’t rise again until the next month. This is often called the Midnight Sun, and the ice camp at the Polarstern has been bathed in light for many days. This is good news for the scientists of Leg 4, who are just now arriving to the floe. The extended daylight will help make all of the research tasks a little bit easier than those Leg 1 and Leg 2 researchers who had to work through the Polar Night. -

This region comprises the two counties Troms og Finnmark and Nordland. If you visit Northern Norway in December or January, you can experience the polar night. The polar night is when the sun is under the horizon the whole day. In Northern Norway, you can see the northern lights in winter. Norway is divided into five regions. Northern Norway is located in the north of Northern lights. Photo: Pxhere.com the country. Trøndelag is located in the middle of the country. Western Norway is During summer, you can see the midnight in the west, and Eastern Norway is in the sun in Northern Norway. The midnight sun east. The region located in the south is is when the sun does not set, and a part of called Southern Norway. the sun is visible above the horizon all night. Every part of the country is divided into counties. There are 11 counties in Norway.
