Processing for Landsat science products can be requested through the following pages:
EarthExplorer – Use EarthExplorer to search and download Landsat ARD availability of the Surface Reflectance and Surface Temperature products. The data are located under the category, subcategory, and listed as .
To begin the order, upload a text file (*.txt) listing one Landsat Level-1 product or one MODIS granuale identifier on each line. Archived Landsat 4-5 TM scenes acquired from August 1982 to May 2012; Landsat 8 and Landsat 7 scenes within one week of acquisition can be processed. The Surface Reflectance Caveats and Constraints section provides more information on these and other restrictions.
After uploading the scene list text file, a number of options can be selected, including:
- Source products (Original input Level-1 product or metadata)
- Top-of-atmosphere (TOA) reflectance, surface reflectance (SR), or TOA brightness temperature (BT) products
- SR-based spectral indices (NDVI, EVI, SAVI, MSAVI, NDMI, NBR, NBR2)
- Customizable output options: data format, reprojection, modifying the image extents, and pixel resizing

All orders submitted through ESPA are processed within 1-3 days, depending on the size of the order. Email notifications are sent after the order is placed, and also after the data is processed and ready to download.
Bulk Download Options for Landsat Science Products:
ESPA Application Programming Interface (API) – The API’s basic functionality allows end-users to use a machine-to-machine interface to query order options, place orders, check order status and acquiring download URLs. The API is implemented as a Representational State Transfer (REST) service using Hypertext Transfer Protocol (HTTPS) and Java Script Object Notation (JSON) and therefore is compatible with most programming languages.
ESPA Bulk Download Client – The ESPA Bulk Download Client is a python-based tool that retrieves all completed scenes per user and/or order and places them into a target directory. Scenes are organized by order. It is safe to cancel and restart the client, as it will only download scenes one time (per directory).
