Changes introduced in Swarm product filename extension

19 January 2017

We inform the Swarm users that starting from today, 19 January 2017 at 11:00 UTC, the following changes have been introduced in the Swarm data production to rationalise the product's filename extensions. There are no changes to files which have already been disseminated.

  • The GPS related L1B products (GPSx_RO_1B and GPSx_RN_1B) are delivered in RINEX format as usual, but the extension changes from .DBL to ".rnx"
  • The Ephemerides (position) related Swarm L1B products (MODx_SC_1B and STRxATT_1B) are delivered in SP3c format as usual, but the extension changes from .DBL to ".sp3"
  • L2 Cat-2 products (EEF, IBI, TEC and FAC) are delivered in CDF format as usual, but the extension changes from .DBL to ".cdf"
  • L2 Cat-1 products will be delivered in their native format. To introduce the change, a production suspension is envisaged for a few days.

In addition, a rationalisation of the L1B CDF global attributes was introduced to remove previous inconsistencies due to the EEF format used during processing.
