Final Globe Protocol
Transcript of Final Globe Protocol
Clouds and Contrails
Examine the clouds and contrails in the sky panoramically and identify how much and what types of clouds/ contrails you see using the GLOBE protocol.
Record which of the ten classifications of clouds and the three types of contrails you see on your Data Sheet.
Recording The Barometric Pressure
Task: Record the maximum voltage reading that can be obtained by pointing your photometer at the sun.
Record the precise time of your measurements, this is very important for future use.
Observe an record cloud conditions, current air temperature, and relative humidity.
calibrating a thermometer
recording temperature on maximum minimum thermometer
Globe sun photometer; digital watch or GPS receiver; Aerosols Data Sheet; thermometer; hygrometer or sling psychrometer; GLOBE cloud chart; barometer; pencil or pen
Task: To measure the amount of pH and rainfall in collected rain gauge. And prepare for use again
Materials: mountain rain gauge, sampling jar with cover, integrated 1 day sheet, appropriate precipitation pH lab guide, and a pen or pencil
Using pH meter
With table salt
read / record water level. Record T if the water level is 0.5 or below. If you spill any water record M
poor water in to jar for pH measuring
record number of days accumulated in the gauge
dry and remount rain gauge
materials: Integrated 1 day data sheet, fine table salt, salt card with 4mm and 5mm circles, stirring rod or spoon, pH meter, pH buffers (4,7, and 10), 3 clean 100 mL beakers or cups, Covered sample jar, latex gloves, pem or pincil, distilled water bottle, tweezers, large salt crystals, 3 clean 100mL beakers or cup
put on latex gloves, calibrate pH meter
rinse elctrode with water
poor 50-30ml of sample rain into clean beaker
sprinkle salt onto card
poor salt into beaker
calculate average measurements and record
rinse beakers and sample jars with distilled water.
In the Field:
- Measure the surface ozone concentration.
- Record cloud conditions, current air temperature, wind direction, and relative humidity.
1 ozone test strip; plastic bag for the test strip; ozone test strip scanner
clipboard; ozone data sheet; pen/pencil; sling psychrometer or digital hygrometer; Field Guides (Measuring Wind Direction; Cloud Cover; Sling Psychrometer or Digital Hygrometer); Globe Cloud Chart; Wind Direction Instrument; instrument shelter key; digital watch
Task: To measure the relative humidity(RH) using a Digital Hygrometer.
Materials: Instrument shelter, thermometer, watch.
Materials: Davis weather machine,Integrated 1-day data sheet
Task: to identify the clouds and contrails in the sky
Materials: Globe cloud chart, and Atmosphere Investigation Data Sheet

1 Cloud Cover and Contrial Protocol
2 Temperature Protocol
3 Precipitation Protocol
4 Humidity Protocol
5 Barometric Pressure Protocol
6 Aerosols Protocol
7 Ozone Protocol
Record time and date on Integrated 1-Day Data Sheet
read and record the level of murcury on the top and bottom of both the minimum and maximum sides of the thermometer
Task: To find your areas air pressure
When using a device which gives you the reading in millimeters of mercury (Such a as the Davis weather machine) , just divide the number it gives you by .75128 to find the number in mbars.
1 Make sure to record your location before making measurements with the sun photometer.
2 The time of the measurements are important in order to calculate the solar position at your site.
3 Include sky conditions, the temperature, and the relative humidity in your measurements.
4 Measure the barometric pressure at your site in order to calculate aerosol optical thickness.
