Add new datasets: EL NINO SEA SURFACE TEMPERATURE/MARINE HEATWAVES

[AparicioSF]

• Water surface temperature (WST) S3

  • [x] #195
  • Data integration
  • COG being prepared by PLES (Diego), difficulties in preparing chunked data, tricky part should be solved
  • focus on summer, june, july
  • [x] Yaml configuration
  • eodashboard integration working

• Ocean heat content for the upper 300m - source

  • [x] Data integration
  • [x] Yaml configuration
  • [x] eodashboard integration working
  • [x] issue with statistical process call

• AMSR-2/AMSR-E SST Monthly mean anomalies - source - this one we are talking with JAXA regarding this dataset

  • [x] Data integration
  • Data was provided as COGs by JAXA and can potentially be integrated by the PLES team
  • Anca asked the PLES team to prioritize loading this dataset
  • [x] Yaml configuration
  • [x] eodashboard integration working (legend missing - to be provided PLES)

@FedericoRondoni could you add the yaml and MD file ?

[santilland]

PLES team to check if data available in openEO, time range 2023-2024 ("worst case" - use landsat data)

[FedericoRondoni]

@AlessandroScremin YAML and MD added

[santilland]

Integration of Ocean heat content looks good:

YAML file for the JAXA dataset ready and uploaded with this pull request https://github.com/eurodatacube/eodash-catalog/pull/183

[santilland]

Hello @FedericoRondoni the WMS request says SST_BY_GCOM-W-AMSR_JAXA not found, was only the yaml file prepared but not the data yet ingested?

[FedericoRondoni]

YAML file for the WST Sentinel-3 data uploaded here https://github.com/eurodatacube/eodash-catalog/pull/183

Hello @FedericoRondoni the WMS request says SST_BY_GCOM-W-AMSR_JAXA not found, was only the yaml file prepared but not the data yet ingested?

Exactly. The data still needs to be ingested

the Jaxa SST products for June to August 2023 have been ingested in SH.

@aapopescu for what concerns the WST from Sentinel 3 L2, is on hold due to the long time needed for LST...we can ingest 2/4 days every day...Now we ingested all june and just started July for LST.

But SST from JAXA are ingested now

[santilland]

@santilland @lubojr look at potential direct integration of data from https://data.earth.jaxa.jp/app/image/v1/?params=%7B%22collection%22:%22https://s3.ap-northeast-1.wasabisys.com/je-pds2/cog/v1/JAXA.G-Portal_GCOM-W.AMSR2_standard.L3-SST.daytime.v4_global_daily/collection.json%22,%22band%22:%22SST%22,%22bbox%22:%5B-79.8047,-84.337,80.7963,76.2641%5D,%22width%22:500,%22height%22:500,%22date%22:%222022-07-09T00:00:00.000Z%22%7D

@aapopescu

• Statistics API call fixed for OHC300_Ocean_Heat_Content_upper_300m (and set unit to be the same as in legend - divide by 10e9 from J to GJ)

[FedericoRondoni]

@lubojr @santilland SST legend added here https://github.com/eurodatacube/eodash-assets/pull/70

[FedericoRondoni]

@AparicioSF to do the MD for ENSST indicator collections/ENSST_by_GCOM-W-AMSR_JAXA

[AparicioSF]

ENSST_by_GCOM-W-AMSR_JAXA

Done.
