Join professional and community scientists in collecting and sharing important data and learn more about your local environment in the process. There are two ways to participate: 1) sign up and contribute as an individual; 2) join as a host-site ambassador to facilitate participation through your community-based organization. Four Protocols to Collect Data for the El Nino campaign. To support GLOBE in this long-term campaign, we are recruiting, training, and equipping participants for four separate but related protocols representing a range of commitments from a light touch to an in-depth experience ,based on the needs and interests of you and your community. The four protocols range from atmosphere to pedosphere observations; from very simple to more complex: The cloud protocol: a quick assessment of the type and density of cloud cover as viewed from the collection site. The surface temperature protocol: uses a simple tool to capture 9 measurements that are averaged to submit a reading to GLOBE. The precipitation protocol: documents rainfall from day to day or more frequently on a rainy day to provide data about rainfall volumes and rates The Soil Moisture Active Passive (SMAP) protocol: provides data about soil moisture temperature that can be used to ground truth a NASA satellite that is in orbit. All of these protocols help us to understand how climate change affects the global water cycle. Changes in the water cycle, such as increased periods of drought and increases in rain or snowfall, significantly impact people’s lives, biodiversity, food production and more. Some regions will see the impact of climate change long before others, but all of us will be affected by changing water patterns in our lifetime. The more granular data we have from citizen scientists, the more we can understand the changes and how to mitigate them.
