The green triangles are measurements (with gray shaded error bars) of tau taken by the Instrument Deployment Camera (IDC) on the robotic arm. East is at 90 degrees, South at 180 degrees, west at 270 and north is 360.Ītmospheric Opacity (or tau): This is a measurement of how much sunlight is blocked by dust in the atmosphere before it reaches the ground. Wind Direction: The black dots show the daily average wind direction depicted in degrees east of north, as if reading a compass. The grey bars show each sol's maximum and the 90th percentile lowest winds as measured by the wind sensors. Wind Speed: The black line shows the daily average wind speed in meters per second at the InSight site. Pressure: The black line shows the daily average atmospheric pressure in Pascals at the InSight site, along with each sol's maximum and minimum pressure on the grey bar. Each sol's maximum and minimum air temperatures are at the top and bottom of the vertical grey bar. The vertical columns of color denote the seasons on MarsĪir Temperature: The black line shows the daily average air temperature in Celsius.The number of days (or sols, on Mars) runs along the bottom of the graph with the most recent day at the right.The Earth months run along the top of the graph.The five datasets on this graph give a full picture of what it might be like to spend a year near the equator on Mars. This graph illustrates seasonal change in Elysium Planitia since InSight landed. Image credit: NASA/JPL-Caltech/Cornell/CAB Seasonal Weather Report A circle in place of a barb indicates a wind speed less than 2.5 meters per second. Full and half flags extending from the barbs indicate the wind speed, with each half flag representing approximately 2.5 meters per second. The barbs extending from each wind speed data point indicate the compass direction of the wind (e.g., a wind blowing from the north will have a barb straight up above the point a wind blowing from the west will have a barb off to the left). Wind speed is shown in meters per second, as measured by the pair of TWINS booms. Wind Plot (not currently being generated): Typical sea-level pressure on Earth is around 101,325 Pascals (1013.25 hPa). Temperature Plot (not currently being generated):Īir temperature is shown in degrees Celsius, as measured by the Temperature and Wind for InSight (TWINS) instrument.Ītmospheric pressure is shown in Pascals, as measured by an air pressure sensor, which is part of the Auxiliary Payload Sensor Suite (APSS). All data points are one-hour averages of the calibrated data from the spacecraft. The corresponding Earth time is also shown at the top of the plot, in Coordinated Universal Time (UTC). Lighter and darker vertical bands indicate daytime and nighttime at the lander, respectively. Numbers along the bottom show hours of local time at the InSight lander (Local True Solar Time, based on Sun angle). Time runs along the bottom of the plot with the most recent data at the right. The plot shows the latest three sols (Martian days) of weather data at InSight’s landing site near the equator of Mars. This plot is being updated daily throughout the duration of the InSight mission. Graph of the Weather Report at Elysium Planitia
