GLOBE Protocol Bundle: Weather

Weather

The purpose of the Weather Bundle is to suggest a group of GLOBE protocols that can provide students and teachers with integrated knowledge of the parameters and processes which control weather and are responsible through their changes, for weather events. (Source: GLOBE Weather Protocol Bundle)

Protocols Include:

Atmosphere

Air Temperature - Measure the current air temperature when an instrument shelter is not available. Current air temperature is measured using a thermometer held in the open air but in the shade for at least 3 minutes.

Supplemental Earth System Data Explorer data sets: 

These temperature data sets allow students to explore monthly temperature averages at different heights in the atmosphere during the daytime and nighttime. They can select different altitudes. They can also research monthly surface air temperature and air temperature anomalies to help put their own data in context.

Barometric Pressure - Students use an aneroid barometer to measure barometric pressure in support of the Aerosols and Water Vapor Protocols.

Supplemental Earth System Data Explorer data sets :

The Earth System Data Explorer does not have barometric pressure data. However, the temperature and cloud coverage data can provide context for barometric pressure data. Temperature and pressure are inversely related. Pressure is related to warm and cold fronts which are also associated with clouds.

Clouds - Observe and report which types of clouds are visible, how much of the sky is covered by clouds, and the opacity of clouds. Also report sky and surface conditions. Each observation is matched to satellite data of clouds taken about the same time and location. Cloud observations can be taken at any time! This Protocol is designed to be flexible and fit into your schedule, classifying, observing, and reporting cloud observations when it works for you. If you observe while a satellite is overhead, you can then receive an email from NASA comparing your observations to satellite data.

Your cloud observations help NASA to better understand the different types of clouds and the effects they have on our Earth’s climate. NASA matches cloud observations to corresponding satellite data. Satellites only see the top of the clouds while you see the bottom. By putting these two vantage points together we get a much more complete picture of clouds in the atmosphere.

Supplemental Earth System Data Explorer data sets:

In addition to cloud coverage data sets, there are data about cloud opacity (how much sunlight clouds absorb and scatter) and phase (clouds contain liquid, ice, or mixture of both types). There are also data sets which students can use to compare the net flow of energy towards Earth with and without clouds to see the impact of clouds on the energy budget. Finally, there are precipitation (amount of snow and rain that reaches the ground) and atmospheric water vapor (the total amount of water vapor above you in the air) data which can be compared with cloud cover.

Precipitation - To determine the amount of moisture input to the local environment by measuring rain and snowfall.

Supplemental Earth System Data Explorer data sets:

Precipitation data are complemented by cloud data and water vapor data.

    Relative Humidity - Students measure the relative humidity using either a digital hygrometer or a sling psychrometer.

    Supplemental Earth System Data Explorer data sets: 

    The Earth System Data Explorer does not house surface relative humidity data. Data sets that can be used to complement investigations of relative humidity are atmospheric water vapor and cloud coverage data.


    Biosphere

    Land Cover Classification - Students locate, photograph, and determine the MUC class for 90 m x 90 m areas of homogeneous land cover.

    Supplemental Earth System Data Explorer data sets: 

    This data set shows the land cover classifications. There are data sets for individual land cover classifications. These data are a snapshot from the late 1990's and early 2000's.


    Hydrosphere

    Water Temperature - Students will measure the temperature of water.
