The best available science data processing algorithms in early 2024 were applied into the operational forward processing and reprocessing of KaRIn data to generate both the PIC0 and PGC0 products. The PIC2 products have resolved several algorithm and product issues that were identified in the PIC0/PGC0 products.

### **SWOT in Space and Time**

[SWOT Track Visualizer](https://whereisswot.onrender.com/) - For more information on the SWOT Track Visualizer tool see the [SWOT Mission Page](https://swot.jpl.nasa.gov/mission/swath-visualizer/).
The following tools shared from the [SWOT Mission](https://swot.jpl.nasa.gov/mission/swath-visualizer/) may be helpful in determining which SWOT data to download for the given time and space focus of a particular application or science question.

#### **Find locations for a date: SWOT Track Visualizer**

You can figure out where the SWOT satellite was or will be on any given day using the interactive [SWOT track visualizer](https://whereisswot.onrender.com/) created by iury Simoes-Sousa. By tracking the satellite's passings, users can find when and where SWOT data may be available, making it easier to plan fieldwork, in situ data collection, and analysis.

#### **Find dates for a location: Search SWOT's Pass-over Time**

CNES has developed a dedicated visualization tool as a quick look at where SWOT has been, where it is, and where it will be. From within the [Binder application](https://mybinder.org/v2/gh/CNES/search_swot/HEAD?urlpath=voila%2Frender%2Fmain.ipynb), select the area of interest and click the Search button to search for SWOT passes. (Note: the user-provided bounding box needs to be large enough to capture a nadir track. Otherwise, no passes will show up.) The results are displayed in a table and the swaths that intersect the area of interest are displayed on the map. Click on the marker to view the pass number.
