The Mars Global Surveyor Radio Science Team will acquire thousands
of profiles of the martian atmosphere during the course of the MGS mission.
The main mapping phase of the mission began in March, 1999. This phase of
the mission concluded successfully, and the mission entered an extended
mapping phase in January, 2001. The atmospheric profiles include precise
temperature and pressure measurements as a function of height above the
martian surface, and will allow Team members to observe the weather on
Mars for more than one complete martian year (687 days).
The Team is sharing this data with the participants in their outreach
program. Students gain access to martian weather data when results are
available, and they may compare the martian weather data with their own
observations of Earth's atmosphere.
Tools to access the martian atmospheric data and to view graphs of the data
and the experimental conditions on Mars when the data were acquired are
available on this Web site. Tools are also available for students to upload
their own measurements of Earth's atmosphere and to view graphs of their
observations. In addition, an extensive set of introductory lessons and
activities are available to acquaint students with the fundamentals of
atmospheres, weather and climate. The site also includes a detailed

and would like to have your classes record their own local weather
measurements for comparison with the data from Mars, please register with

Visit this page to find the dates for which data are
available, and use these tools to retrieve the data
and to generate graphs of the data and the conditions under which it was
acquired. The latest martian weather
observations may also be seen at a glance, along with maps of Mars
showing the locations of all of the atmospheric measurements to date. You
may click on the location of any observation to see the surface weather
information for that point! Selected temperature and pressure profiles of
the martian atmosphere are also available. These profiles show the vertical
structure of the atmosphere at the time and place where a radio occultation
experiment was conducted.

- This department contains dozens of questions about the atmospheres of Earth
and Mars which participants in the MGS Radio Science Team education outreach
program may answer based on the martian meteorological data provided to
them by the MGS RST and data from Earth's atmosphere recorded by outreach
program participants. Many of the questions are not easy!
Introductory Lessons & Activities
- Together with a local teaching consultant, an extensive set of
lessons and activities have been developed to provide program
participants with an introduction to atmospheres, weather and climate.
Participants who study the lessons and perform some or all of the
activities before they first access the martian atmospheric data
will be in a position to better understand the data and will be able
to make more meaningful comparisons between the martian data and their
own observations of Earth's atmosphere.
Data Transfer & Visualization Tools
- Simple forms have been created which allow students to transfer
martian atmospheric data from the Web server at Stanford, and to upload
their own local atmospheric measurements to the outreach program database
at Stanford. Another form has been created which allows students to retrieve
their own atmospheric measurements from the Stanford Web server. Forms have
also been created which allow students to generate and view graphs of the
martian atmospheric data and of the experimental conditions on Mars when
the data were acquired, and to generate and view graphs of the atmospheric
measurements of all of the program participants.
Daily Martian Weather Report
- This Web site contains information about the MGS Radio Science Team and
their investigation of the martian atmosphere with the radio occultation
technique. It describes how the Team uses radio transmissions from the
MGS spacecraft to probe the martian atmosphere and determine its structure.
