RETIGO Data Entry

RETIGO is a free, web-based tool that is optimized to visualize air quality data collected while in motion (walking, biking, or on a vehicle). It is intended to be used by anyone to explore their collected data and can also optionally bring in data from nearby air quality and meteorological stations. Enter your data file below, or visit the tutorial page for help in getting started.

RETIGO can be used by anyone to explore the data that they collected. To collect the data, monitoring equipment is needed and ranges in price from ten dollar sensors up to professional grade equipment costing tens of thousands of dollars. EPA's Air Sensor Toolbox site has an array of information on emerging technologies for air monitoring.

RETIGO reads plain text files, which can be either comma or space delimited. The data columns must be in a form that RETIGO can understand. Enter your data file below, or visit the tutorial page for help in getting started. General information about RETIGO can be found on the RETIGO website. Problems running RETIGO?

Due to the complexity and size of satellite data, it may take several minutes to finish loading one day's worth of data. Please be patient.

Data in the scatterplot is automatically aggregated to the hour. To ensure consistency between the scatterplot and the timeseries plot, be sure to check the timeseries plot's "Hourly" option.

The data flagger is an advanced feature of Retigo used to detect and/or exclude data points that fail certain testing criteria. It is the responsibility of the user to ensure that the test parameters are set correctly and to make the final judgement about the validity of the flagger results. Each test can be independently enabled or disabled using the checkboxes. The tests include:

Constant	Data is flagged if the specified number of values occur sequentially (i.e. the data remains constant).
Missing	Data is flagged if the specified number of missing data values (-9999) occur sequentially.
Outlier Stat	Data is flagged as a statistical outlier if the standard deviation is a factor of X more than the mean.
Outlier Spike	Data is flagged as a statistical outlier if the standard deviation is a factor of X more than the mean within the specified time window.
Above Conc	Data is flagged if the value is above the specified threshold.
Below Conc	Data is flagged if the value is below the specified threshold.
User Invalidated	Data is flagged if it occurs within the specified time window.

Before your file is exported, we need to ask a couple of questions about your data.

Was your data collected above ground level? Yes No

Which variable, if any, contains altitudes above mean sea level in meters?

Which variable, if any, contains altitudes above ground level in meters?

The specified data files must have the same columns in order to merge the file streams.

Share a data file

You may upload a data file into the RETIGO data repository for other people to view.

Perhaps you are interested in sharing your data for project teammates to easily access, or with the broader public for others to explore environmental data. You are welcome to store your RETIGO-formatted data here. Please note the following conditions apply:

We ask for some information about you and your measurements – we will use the information about your measurements to allow others to search for your data. Your contact information is for us to be able to contact you if needed about your data and will never be shared.

Any data you do provide will be made available to RETIGO users via our data search page. We do not have private data storage available at this time, so please only share your data with the full understanding that it will be made open access.

Terms and Conditions:

It is the responsibility of the user to format their data according to RETIGO standards and verify the quality of their data. Uploading data to RETIGO does not indicate any level of quality assurance nor endorsement of the data by the U.S. Environmental Protection Agency.

It is the responsibility of the user to read and evaluate the limitations and intended use of the RETIGO data visualization tool.

Any data uploaded to RETIGO will be made open access and there is no private access option. Personal identifiers or sensitive data should not be incorporated into a data set published for open access. The U.S. Environmental Protection Agency reserves the right to remove uploaded data or deny access to upload data at any time.
