The NOAA Laboratory for Satellite Altimetry's (LSA) sea surface height team produces 0.25-degree longitude/latitude Level-3 significant wave height, wind speed, and sea level anomaly (SLA) daily datasets by applying optimal interpolation to along-track satellite observations over the global ocean from a constellation of radar altimeter missions. There are 144 granules per 24 hr interval, with a total data volume of ~25 GB/day for L2P, and ~0.4 GB/day for 元U.Ġ Hours <= 24 Hours (NRT), 24+ hours (Delayed)Īlong-track significant wave height, wind speed and sea level anomaly from multiple altimeters The data are reported in 10 min granule files in NetCDF4 format, compliant with the GHRSST Data Specifications v2 (GDS2). These VIIRS SST data are produced using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) SST system, from the afternoon NPP and N20 satellites, in two formats: L2P and 元U (uncollated). MODIS data can reprocessed in STAR, for the full Terra and Aqua missions, if there is users' interest. The data are not archived and only available at this CoastWatch page as a 2week rotated buffer. Only near-real time (NRT) data are produced at STAR, with a 3-6 hours latency. The MODIS SST data are produced from Terra and Aqua satellites using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) enterprise system (Ignatov et al., 2016). The RAN2 dataset is documented in (Petrenko et al. All NOAA orbits are not controlled and evolve in time. Out of ten satellites, seven (N07/09/11/14/16/18/19) were initially launched into afternoon orbits (1:30pm/am), two (N12/15) into early-morning orbits (7:30pm/am), and one (N17) into mid-morning orbit (10am/pm). At the time of release, it covers from to and will be periodically extended as new L1b data from N15/18/19 arrive. RAN2 is produced from 5 AVHRR/2s (onboard N07/09/11/12/14) and 5 AVHRR/3s (N15/16/17/18/19) using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) enterprise system v2.81. ĪVHRR GAC Reanalysis 2 (RAN2) dataset is an improved and extended version of AVHRR GAC RAN1 (Ignatov et al., 2016). Metop-A mission officially ended at and the production of the ACSPO SST for the Metop-A ended at due to data degradation on. The data are being archived at PO.DAAC, and also available at this CoastWatch page as a 2 weeks rotated buffer. Currently, near-real time (NRT) L2P and 0.02° 元U (gridded uncollated) data for Metop-A, -B and -C is produced at STAR (with ~2 to 6hrs latency). The AVHRR FRAC SST data are produced from AVHRR/3s onboard Metop-A, -B and -C satellites using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) v2.80 enterprise system, described in (Ignatov et al., 2016). ![]() There is a plan to reprocess the AHI data, for the full Himawari-8 mission. The data is also available at this Coast Watch page as a 2week rotated buffer. The data is archived with PODAAC with start date 2019-Oct-16. The data are available in NetCDF4 format, compliant with the GHRSST Data Specifications v2 (GDS2). Currently, only near-real time (NRT) data are produced at STAR, with a 2-6 hour latency (typically closer to 2 hours). The AHI SST data are produced from Himawari-8 geostationary satellite using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) v2.70 enterprise system. Currently, the data are archived on PO.DAAC and available at this Coast Watch page as a 2week rotated buffer. A Reanalysis (RAN) dataset for GOES-16 is also available. Currently, near-real time (NRT) data are produced at STAR, with a ~2-6 hour latency. The ABI SST data are produced from GOES-16 and GOES-17 satellite using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) v2.7x enterprise system. The AM and PM lines correspond to 9:30am/pm and 1:30am/pm equator crossing times, respectively. The Daily line combines PM and AM (day and night) SSTs into a single daily 元S SST that is normalized to 1:30am viewing conditions. The 元S-LEO family is organized into three lines: PM, AM and Daily. NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) 元S-LEO SST is a family of multisensor gridded ("元") 0.02º resolution super-collated ("S") products. ![]() ACSPO Global 0.02º Gridded Super-collated SST and Thermal Fronts from Low-Earth-Orbiting Platforms (元S-LEO)
