# Introduction The online processing is optional. Customers can opt out of having their data uploaded to Skaha's server for processing. The following steps are performed as part of the online processing: * Filtering * Gain and drift corrections * Gridding onto a regular grid of latitude and longitude * Separation of polarized and unpolarized components * Conversion of radiometer output into volumetric water content using a land-surface model * Provision of raw data, processed data, and graphs in a Google Drive folder accessible to the customer only Even though users may want to perform their own data processing, letting the raw data run through Skaha's processing chain will give quick feedback on the data quality: ![](/files/McjhEqu128PXULYoUuoA)![](/files/No3BuPemtcV6PNLlWBCv) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://skaha-labs.gitbook.io/documentation/online-processing/page-4.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
