B2SAP data for the NOAA CSL Portable Optical Particle Spectrometer (POPS) instrument is archived by location:
When accessing POPS aerosol size distribution data on this site, please ensure you review the file header carefully. Due to telemetry updates, it is possible that the total number of size bins can vary between 15, 20, or 36 bins and the diameter bin edges can occasionally differ - even for a consistent number of bins - between launches due to instrument configuration updates. These changes may affect how size-resolved quantities should be interpreted or compared across profiles. Always refer to the header information to confirm the appropriate bin definitions for your analysis.
B2SAP data is included with NOAA GML Water Vapor. When an ozone sonde was launched at the same time, it is included in the water data file. All the ozone and water vapor data that included a POPS is archived by location:
