GLOBE Science Values

  Accuracy is critical.   Do your best to get it right. The GLOBE protocols are important. They insure we all do the measurements in the same way. Our students need to care about the measurements. We do not want robotic data takers. We need active student observers.

Calibrate instruments periodically.

 

 Use GLOBE instruments (they are standardized)

Teams of students can make multiple measurements and compare them.

  Consistency is the key to making the data valid. Once data is lost, it can never be collected again.

The protocols specify frequency for measurements.

All protocols are on the CD and  on the Web.

  Trained teachers monitor GLOBE measurements for their school.

 

  Persistence. We have no choice but to observe the Earth and watch it change.  Atmospheric data is most valid when we have daily coverage (that's weekends too). 

•  Be persistent as a community - take pride in your school data record.

• Each measurement is recommended to be taken at the frequency needed to see the phenomena.
  

• The value of the measurements is in the density of the data.
• Frequent and regular measurements lead to better monthly and accumulative averages.
  
• From a statistical point of view, it is better to have several solid months of data during the school year than spotty coverage over the year.

 

  Coverage. In order to detect change science needs to describe the Earth's environments as completely as possible.

• At no other time in history has there been an attempt to cover as much area of the Earth as intensively as we will through the GLOBE program.
  

• There are many micro climates in our environment. The more measurements, the better and more complete the data set.

Only your school can correct data errors... no one else can change data you have entered.
