New! Dr. Brooks' Summary of GLOBE ONE Pyranometer Data
The GLOBE ONE Field Campaign is in the process of collecting a dataset that will allow scientists and students to answer the research questions that have been asked.
There are four main methods of data collection being employed to collect this dataset, namely:
The student-collected data come from sites located throughout Black Hawk County, while the volunteer-collected hydrology data come from 6 specially chosen hydrology sites, and the logged data come from 10 specially chosen .intensive. sites on farmland and prairie in Iowa. Intensive means that the site will have a continuous data collection from automated weather stations.
All data collected through GLOBE ONE are available to the public. We encourage you to use this dataset to perform your own investigations.
Students at schools, and some volunteers, throughout Black Hawk County are collecting a myriad of measurements that serve to define the environment of the County. These measurements encompass a variety of investigation areas such as atmosphere, hydrology, soil, land cover/biology, and seasons.
The following map shows the location of GLOBE ONE school sites:

Volunteers are collecting hydrology data at 6 sites that were specially chosen to represent the runoff from the different tillage types being investigated by the GLOBE ONE Field Campaign. GLOBE ONE owes thanks to the IOWATER Volunteer Water Quality Monitoring Network for their assistance in recruiting these volunteers.
A map of the locations of these sites will be posted soon.

A MUC-a-THON is an intense collection of land cover data. In order to help build a land cover map of Black Hawk County, a GLOBE ONE MUC-a-THON was held on October 9th, 2004. It involved students, teachers, and a Girl Scout collecting data with training and supervision from GLOBE ONE scientists. This first MUC-a-THON will be followed up a by a larger event in the spring.

Data is being logged with Davis Vantage Pro Weather Stations mounted on poles that can be adjusted in height to account for the growth of the vegetation. The weather stations are located at 10 "intensive" study sites; four of which are no-till agriculture fields, 4 of which are conservation tillage agricultural fields, and two of which are prairie. These sites are defined in the GLOBE database.
The following map shows the location of the 10 "intensive" study sites:

Sample graph of automated GLOBE ONE logged data from John Deere Prairie for June 2004.
Six of the GLOBE ONE automated weather stations were setup at Colorado State University prior to being installed in Iowa. The purpose of this setup was to see how well the sensor readings from those stations would match up. Scatter plots were made of the temperature, relative humidity, and pressure readings collected by these stations. While there is some noticeable scatter in both the humidity and pressure plots, all points fall within the NIST certifications for the sensors. You can view an these plots along with the data used to generate them at (in an Excel spreadsheet) by clicking here.
