About AρρEEARS:

AρρEEARS offers users a simple and efficient way to access and transform data. By enabling users to subset data spatially, temporally, and by layer, the volume of data downloaded for analysis is greatly reduced. Sample requests submitted to AρρEEARS provide users with data values and associated quality data for a variety of remote sensing data products. Interactive visualizations with summary statistics of the sample results are provided within the application to allow the user to preview and interact with their sample before downloading the data.

Step-by-step instructions for how to use AρρEEARS and a full listing of products available can be found on the AppEEARS Help page. Additional resources for using AρρEEARS and its services are available on the LP DAAC E-Learning page. For questions, contact LP DAAC User Services (
