LAADS Web Classic Services (LWS Classic) is an Application Programming Interface (API) that allows users to search, order, and download MODIS Level 1 and atmosphere data products through a programmable interface.
The Web Service Description Language (WSDL) XML document describes the operations, parameters, and data structures used in the web service.
A description of the LAADS Web Classic Services API and a Quick Start Guide are also available on the Tools & Services page of the LAADS DAAC.
NOTE: The API-V2 API is meant to eventually replace this "LWS Classic" API, which will be deprecated in the future.
