9. Keep a daily weather chart for three weeks. Include the following:
This requirement is very similar to one found in the Explorer IA curriculum, except that Explorers are required to keep these records for two weeks and take readings twice a day. You can also combine these requirements with those in the Weather honor. If you forget to take records for a day, do not despair. As long as you have 21 readings, you can count this as three weeks.
a. Amount of precipitation (Secure this either from your own home-made device or from official records.)
If you chose to make a rain gauge in the Weather honor, you can use that here. Otherwise, you can find official records online in many places, including The Weather Underground. Enter your zip code, and all the readings needed will be displayed (except for cloud formations).
