Happy Anniversary to Us! It's been two years and in this week's roundup we are walking down memory lane. 1. ANNIVERSARY: Our team has grown and changed somewhat over the last two years. As has the app: We first started with one tool: Clouds (back in the fall of 2016). Then added the option of sky color and more to Clouds in March 2017. Then came Mosquito Habitat Mapper in the spring of 2017. Recently, The GLOBE Program and the GLOBE Observer app have joined with the Department of State to help in the fight against zika with the GLOBE Zika Education and Prevention Project. This project is on going, but already has trained many in mosquito-disease-prone countries.  >>
