1. Globe Protocol By: Hannah Arcilla, Julissa Netro, Savannah Kari, Riley Snowder & Sandra Campero-Vohs

2. Cloud Type & Contrail Type Protocol Task: To see which of the ten types of clouds and how many of each of the three types of contrails are visible. Materials needed: ● Atmosphere Investigation Data Sheet ( Cloud/Ozone/Aerosol Data sheet) ● GLOBE Cloud Sheet ● Observing Cloud Type ( in Appendix) In The Field: 1.Look at all the clouds in the sky, everywhere, even straight above. Careful not to look directly at the sun. 2.Identify the types of clouds that you see using the GLOBE cloud chart and the definitions found in Observing Cloud Type. 3.Check the box on your Data Sheet for each and every cloud type you see. 4.There are three types of contrails. Record the number of each type you see.

3. Rainfall Protocol Measure the amount of the rain that has collected in your rain gauge. Measure the pH of the rain Prepare the rain gauge to collect more rain ****If there is overflow of water in tube remove measuring tube from overflow tube and read the level water in measuring tube (eyes level with meniscus)
