Based on these measurements, following the GLOBE GPS protocol and similar averaging procedures improves the precision of position and elevation estimates by about a factor of two. Biases (being too high or too low) are harder to identify, but the … Continue reading →

If you’ve used a GPS unit, you know that the elevation readings vary faster than latitude or longitude readings. Sometimes the elevation readings change rapidly. Thus, when I took my GPS readings, I wrote down the elevation, than I wrote … Continue reading →

Those of you who have taken GPS measurements to characterize your GLOBE observation site know that the “elevation” on the GPS unit often varies a great deal. That’s one of the reasons the GPS protocol requires that you take five … Continue reading →

In GLOBE, you use careful measurements to learn things about our environment just as scientists do. Also, some of the data you take for GLOBE is used by scientists. Finally, what you learn from GLOBE about how to take measurements … Continue reading →
