UAVSAR Data Consultation
I'm writing to ask the UAVSAR data information in ASF data search webset (https://search.asf.alaska.edu/). When I search for UAVSAR data in Mondah, Gabon site acquired on 03/06/2016, there are 18 scenes. Such as, UA_Mondah_27080_16013_001_160306_L090_CX_01, UA_Mondah_27080_16013_001_160306_L090_CX_02...UA_sixtym_27082_16013_009_160306_L090_CX_01...What are the naming rules for the scenes? What's the difference between CX_01 and CX_02?
In UAVSAR JPL website (https://uavsar.jpl.nasa.gov/cgi-bin/data.pl), the UAVSAR data in Mondah, Gabon site acquired on 03/06/2016 is named Mondah_TM270, consists of 9 scenes. Are the data in this two websites the same? What the differences between these 18 scenes and 9 scenes?
Additionally, is there any technical reports or documents of 2016 NASA AfriSAR campaign?

Re: UAVSAR Data Consultation
UAVSAR data available from ASF have been processed at JPL and sent to ASF for distribution. No further processing is done once a product is received at ASF. The only change made is to add a UA_ prefix to a JPL product name.
Documentation for the UAVSAR products is available from JPL, and this includes the file naming schema: For the PolSAR products you included as examples, the _01 and _02 part of the filename indicates there are two processing versions available for the same scene.
The way the JPL website displays the products for a scene and the way ASF bundles the products is different, but the number of products is the same.

Re: UAVSAR Data Consultation
Thank you for your documentation. Now I know the numbers 01 and 02 indicate the processing version number, the first/second interation of processing. For example, if I use the data 01 or 02 to do the PolSAR forest parameter inversion, will the experimental results the same? Does the processing version I choose effects the inversion performance?

Re: UAVSAR Data Consultation
Newer versions should reflect improvements/enhancements/corrections to the processing algorithm. I would suggest that you pick the latest version and only use these data for your analysis.
