 Refer to the [Searching page of the ASF Data Search Manual](https://docs.asf.alaska.edu/asf_search/searching/)
  for more details on available search filters and their possible values.
 
+### Search by data maturity
+
+Filter NISAR data by validation/calibration status by using the `dataMaturity` parameter in your search. You can specify either 'PROVISIONAL' for [calibrated NISAR PROVISIONAL](#nisar-provisional-data-july) data or `BETA` for [pre-calibrated NISAR BETA](nisar-sample-data-feb) data. 
+
+To search for PROVISIONAL products, utilize the following Python code:
+
+```python
+import asf_search as asf
+
+results = asf.search(dataset='NISAR', dataMaturity='PROVISIONAL')
+``` 
+
+To search for BETA products, replace `PROVISIONAL` with `BETA`, as shown below. 
+```python
+import asf_search as asf
+
+results = asf.search(dataset='NISAR', dataMaturity='BETA')
+```

 ## Download data
 
 Downloading NISAR data requires authentication through [Earthdata Login (EDL)](https://urs.earthdata.nasa.gov/). For more information, see @earthdata-login.

 NISAR PROVISIONAL datasets were released July 20, 2026. These products are fully calibrated and have undergone validation at a limited set of sites around the world. These datasets are designated as PROVISIONAL pending more complete validation over larger areas around the globe, but are a significant improvement over the [BETA products](#nisar-sample-data-feb) released in Feburary 2026.

 Prior to the release of the PROVISIONAL products, a selection of pre-calibration BETA NISAR L-band products was made available through the ASF DAAC. These BETA products were released to allow users to develop workflows to access the data and metadata for each product type, to become familiar with the characteristics of the L-band products, and to begin working with the data in a substantive way.

 Additional validation will take place using the provisional data, resulting in algorithm improvements. Once the products are fully validated, the NISAR project will transition to generating validated products with a new version of the processor and begin a reprocessing campaign. These validated products will supersede any earlier versions of the data in the archive.
 
-This reprocessing campaign will generate new versions of Level 0-3 products from the global backlog of all L-band data collected during the science phase of the mission. Data products will be continually published to ASF and made publicly available as they are generated during the reprocessing effort, which is expected to be complete by the end of 2026.
