How to...

• Using IESRE's two-channel reflectometer
• build a pyranometer
• build a sun photometer
• buy solar and atmosphere monitoring instruments from IESRE.
• calculate aerosol optical thickness if you know relative air mass or if you know position and time
• calculate Ångstrom exponent and turbidity coefficient
• calculate dewpoint temperature from air temperature and relative humidity
• calculate (approximately) total precipitable water vapor from location, air temperature, and relative humidity
• calculate distance between two points on Earth's surface
• calculate electromagnetic energy radiated by an object, as a function of its temperature
• Calculate solar energy reaching Earth's surface
• convert sea level ("weather report") pressure to station pressure
• count pixels in a black-and-white image
• create KML files for displaying geo-located data in Google Earth
• enter the GLOBE Web site
• find AERONET data online
• find GLOBE aerosol optical thickness data online
• find GLOBE water vapor data online
• find GPS-MET water vapor data online
• find solar noon and day length at your location
• find times for satellite overflights of your location
• find weather data (including barometric pressure) for your location
• learn about measuring solar transmission through the atmosphere
• Set your clock or watch accurately
• use a GLOBE sun photometer
