A Sentinel-1 annual mosaic over Viti Levu, Fiji. This is mean VV in decibels. (I think in decibels!)

What is the most useful way to do an annual summary product from Sentinel-1?

[Matt Garthwaite @mcgarth83]

@alexgleith Nice one Alex. Good to see that you can't see overlaps or discontinuities over the land

[CEOS-ARD @CEOSARD]

New CEOS-ARD Dataset! @CSIRO's 14 different #NovaSAR Normalised Radar Backscatter products, including ScanSAR and StripMap modes, in various polarsations, resolutions and swath widths. Congratulations to the team!

The @capellaspace Capella 5 radar sat reentered on Feb 23. Of the 8 Capella sats launched so far, it looks like the first 5 are on their way to reentry:

@Nozadkhalil @amylauraparker still the case?

At the @CEOSdotORG SAR Calibration/Validation workshop this week. Big space agencies discuss SAR data quality, higher level products & more. Thanks @csa_asc for hosting! 🛰️

@capellaspace, @mouthofmorrison, @ICEYEfi we miss you here 😢. Please join us next time!!

🆕soil moisture maps at 1 km resolution with @CopernicusEU #Sentinel1 data😱
This degree of resolution will make it possible to assess the availability of water and better predict drought over narrower swathes of land: https://t.co/YE5ysMIROG

A relatively new installation at @CSIRO Boorowa farm for the Australian CosmOz Soil Moisture Monitoring Network. Good work @TERN_Aus to support this important work in the southern cropping region.

Sad news, but I think we were all resigned to Sentinel-1B not being revived 😭

[Simonetta Cheli @SimonettaCheli]

We have just announced with the European Commission that the @CopernicusEU #Sentinel1 B satellite can no longer deliver radar data.

This were the conclusions of the Anomaly Review Board:

Decision-makers need to be confident in the data they use for mitigation strategies and policymaking.
👉TRUTHS, a new @esa mission, will do just this – and, now having passed an important milestone, it is one step closer to becoming a reality https://t.co/TiA6MHvJlZ

Papua New Guinea's 2nd-largest city, Lae, sits adjacent to a major active tectonic plate boundary.

Oral histories talk about a major tectonic event 250 years ago, which changed the course of a river flowing through Lae today.
