  3. Before we can predict what a storm will do in the future, we need to know what the storm, the atmosphere, and the ocean look like right now! Radiosondes: Instruments attached to weather balloons that transmit temperature, humidity, & wind data back to the ground. These balloons are launched globally twice a day. Aircraft:Commercial aircraft regularly report weather data. NOAA “Hurricane Hunter” aircraft penetrate hurricanes to gather valuable data on the storm. Satellites:Gather data on clouds, water vapor, and land & sea surface temperatures. Observational Tools Surface:Thousands of weather stations across the globe report weather conditions every hour.
