Since January 2024 the PPS has been running the GPM near-realtime (NRT) radar Ku, Ka, DPR and the combined products with an interim version of the post-boost radar algorithms. This was designated with the data product version V07X (experimental). JAXA and the radar algorithm team have developed the final post-boost V07 algorithm and will be delivering this on 5 March 2024. We will start using the new algorithms with the arrival of the V07C radar Ku/Ka 1B data from JAXA. The L2 Ku/Ka/DPR and combined products will then also change the data product version to V07C. The algorithm ID for combined...

On 16 January 2024, JAXA MOS will begin sending an NRT version of L1B Ku and Ka radar. PPS NRT will begin producing L2 KU, KA, and DPR radar products. It will also begin producing combined GMI/radar products. All these products will have the data version V07X. The X is to designate that this is not the final code for radar products including boost adjustments but an early one to allow resumption of GPM NRT. The final version will arrive in March 2024. The algorithm versions for the radar products will also change. So, if you retrieve radar products based on file names, you should not use the...

On Dec. 5 2023, the DPR was successfully returned to science mode at 16:30 UTC, then GMI was successfully brought online at 19:30 UTC. The spacecraft final configuration was completed at 20:30 UTC, returning the GPM Core Observatory to full science mode and resuming science data production.

On Dec. 1, 2023, at 7:43 p.m. ET (Dec. 2 at 00:43 GMT) the Global Precipitation Measurement Core Observatory (GPM-CO) satellite transitioned to Sun Point Mode (SPM) via onboard fault management response due to excessive attitude errors. Reaction Wheel #5 showed anomalous behavior and was taken out of the control loop during the reconfiguration. It is unclear currently whether this was the cause, or a result, of the attitude error. Subsequently, a solar array pointing error required additional recovery work. This condition has stopped the collection of science data from both the GMI and DPR...

The GPM Mission Operations have successfully executed Orbit Raise Burn #2 for the GPM Core Observatory (GPM-CO). The maneuver performance was NOMINAL. Burn Start: 17:22:42 UTC* Burn End: 17:32:32 UTC* Duration: 590 seconds *slightly earlier than the planned time stated yesterday – adjusted to optimize altitude-raise performance and subsequent operational events. This completes the GPM-CO altitude-raising process; subsequent work will focus on returning the data products to regular production with as little difference from pre-boost behavior as possible. Note that DPR data will be held pending...
