GCOM-C/SGLI L3 Binned Normalized water leaving radiance (NWLR L530) (8-Days,1/24 deg)

GCOM-C/SGLI L3 Binned Normalized water leaving radiance (NWLR L530) (8-Days,1/24 deg) dataset is obtained from the SGLI sensor onboard GCOM-C and produced by the Japan Aerospace Exploration Agency (JAXA). GCOM-C is Sun-synchronous sub-recurrent Orbit satellite launched on December 23, 2017, which mounts SGLI and conducts long-term global observations of geophysical variables related to the global climate system across 28 items including aerosol and vegetation over 4 areas of atmosphere, land, ocean, and cryosphere. The data will be used to contribute to higher accuracy of global warming prediction. The SGLI has swath of 1150 km in the visible band and 1400 km in the infrared band. Level 3 products are defined to be products derived from Level 1B and Level 2 products by statistically processing the Level 1B and Level 2 products in time and space domains.This dataset is 8 days binning statistics product by reducing the spatial resolution to 1/24 deg with EQA projection. This dataset includes the upwelling radiance just above the sea surface at 530 nm (NWLR_530) and QA_Flag. The physical quantity unit is W/m^2/str/um. The stored statistics values are average (AVE), root-mean-square (RMS), maximum value (MAX), minimum value (MIN), number of input data (Ninput), number of used data (Nused), date of observation (Date), and quality flag (QA_flag). The provided format is HDF5. The Spatial resolution is 1/24 degree. The statistical period is 8 days, also 1 day and 1 month statistics are available. The projection method is EQA.

Aqua/AMSR-E L3 AMSR2 Format Total Precipitable Water (1-Month, 0.25 deg)

Aqua/AMSR-E L3 AMSR2 Format Total Precipitable Water (1-Month, 0.25 deg) dataset is obtained from the AMSR-E sensor onboard Aqua and produced by the Japan Aerospace Exploration Agency (JAXA). Aqua of NASA was launched on May 4th, 2002 in Sun-synchronous sub-recurrent Orbit. Aqua observes various kinds of physical phenomena related to water and energy circulation from space. Aqua data promoted the research activities for interactions between the atmosphere, oceans and lands, and their effects on climate changes. AMSR-E scans the Earth's surface by mechanically rotating the antenna and acquires radiance data of the Earth's surface. Each frequency band is monitored by vertical and horizontal polarized wave. It conically scans and keeps an angle of incidence on the earth surface (a nominal of 55 degrees) and accomplishes a swath width of about 1450 km. The AMSR-E reached its limit to maintain the antenna rotation speed necessary for regular observations, and the AMSR-E restarted its observation in slow rotation mode (2 rotations per minute) on December 4, 2012. However, the AMSR-E reached its limit to maintain the antenna rotation speed necessary for slow rotation mode and it automatically halted its observation and rotation on December 4, 2015. Level 3 data inputs level 1B and level 2 data and projected to the map in accordance with the specified projection technique (Equi-Rectangular (EQR) or Polar Stereographic (PS)), and then averaged temporally and spatially. These statistical values are computed for observation data on ascending orbit and descending orbit respectively. This product includes monthly mean Total Precipitable Water (TPW). PWI (water vapor index) is converted to total water vapor content (PWA, kg/m^2) using a look-up table, which is designed as the provability of PWA with AMSR retrievals is equivalent to that of PWA with radio sonde. The physical quantity unit is kg/m^2. The following Static information is included: Standard_Deviation: standard deviation value for each pixel. This item is only stored in monthly product. Average_Number: the number of valid physical quantity data (except error and missing) which was used to determine "Geophysical Data". Total_Number: the number of physical quantity data included in the grid (include valid and invalid). The provided format is HDF5. The spatial resolution is 0.25 deg. The statistical period is 1 month. The current version of the product is "Version 8". The projection method is EQR. The generation unit is global.
North Atlantic Ocean Chlorophyll-a time series and trend from Observations Reprocessing

'''DEFINITION'''The time series are derived from the regional chlorophyll reprocessed (REP) products as distributed by CMEMS which, in turn, result from the application of the regional chlorophyll algorithms over remote sensing reflectances (Rrs) provided by the ESA Ocean Colour Climate Change Initiative (ESA OC-CCI, Sathyendranath et al. 2019; Jackson 2020). Daily regional mean values are calculated by performing the average (weighted by pixel area) over the region of interest. A fixed annual cycle is extracted from the original signal, using the Census-I method as described in Vantrepotte et al. (2009). The deseasonalised time series is derived by subtracting the mean seasonal cycle from the original time series, and then fitted to a linear regression to, finally, obtain the linear trend. '''CONTEXT'''Phytoplankton – and chlorophyll concentration as a proxy for phytoplankton – respond rapidly to changes in environmental conditions, such as temperature, light and nutrients availability, and mixing. The response in the North Atlantic ranges from cyclical to decadal oscillations (Henson et al., 2009); it is therefore of critical importance to monitor chlorophyll concentration at multiple temporal and spatial scales, in order to be able to separate potential long-term climate signals from natural variability in the short term. In particular, phytoplankton in the North Atlantic are known to respond to climate variability associated with the North Atlantic Oscillation (NAO), with the initiation of the spring bloom showing a nominal correlation with sea surface temperature and the NAO index (Zhai et al., 2013).'''CMEMS KEY FINDINGS'''While the overall trend average for the 1997-2021 period in the North Atlantic Ocean is slightly positive (0.16 ± 0.12 % per year), an underlying low frequency harmonic signal can be seen in the deseasonalised data. The annual average for the region in 2021 is 0.25 mg m-3. Though no appreciable changes in the timing of the spring and autumn blooms have been observed during 2021, a lower peak chlorophyll concentration is observed in the timeseries extension. This decrease in peak concentration with respect to the previous year is contributing to the reduction trend.'''DOI (product):'''https://doi.org/10.48670/moi-00194
Envisat AATSR Averaged Surface Temperature (AST) Product [ATS_AR__2P]

The Averaged Surface Temperature (AST) Product contains averaged geophysical data at two different resolutions, and with respect to two different averaging schemes. Measurement data sets at resolutions of 0.5 by 0.5 degrees and 10 by 10 arcmin with respect to a latitude/longitude grid provide continuity with existing ATSR products.  Other data sets contain data averaged over equal area cells of 50 by 50 km and 17 by 17 km aligned with the satellite ground track. Both top-of-atmosphere and surface data sets are provided. The surface temperature data sets provide, for sea cells, nadir and dual view sea surface temperatures, and for land cells, land surface temperature and NDVI. Cloud data is also included. No ADS are included in the AST product; auxiliary data is contained within the MDS. The data sets of the AST product are arranged by surface type and resolution.  This product is a continuation of ERS ATSR data.  The 3rd reprocessing of AATSR data was performed in 2013; the processing updates that have been put in place and the scientific improvements are outlined in full in the User Summary Note for the Third Envisat AATSR Reprocessing  https://earth.esa.int/eogateway/documents/20142/37627/IDEAS-VEG-OQC-REP-2148-%28A%29ATSR-Third+Reprocessing-Dataset-User-Summary-v1-0.pdf
Envisat AATSR ARC Level 3 products [ATS_AVG_3PAARC]

The recommended AATSR Level 3 products for Sea Surface Temperature (SST) applications are the ARC (ATSR Re-processing for Climate) Level 3 products. ARC reprocesses the ATSR multi-mission archive using new cloud detection and SST retrievals to produce a homogenous record of sea surface temperature. The main ARC objective is to reduce regional biases in retrieved SST to less than 0.1 K for all global oceans while creating a very homogenous record with a stability (lack of drift in the observing system and analysis) of 0.05 K per decade. ARC products are available for ATSR-1, ATSR-2 and AATSR. ARC products are provided in netCDF format and contain data for both the skin SST and the SST estimated for depths of 0.2 and 1.0 m (corresponding approximately to drifter and moored buoy depths). The AATSR estimated depth SSTs are adjusted to a local equatorial crossing time of 10:30 (approximately half an hour after observation), to provide continuity with ATSR-1 and ATSR-2 data. The ARC project was led by Chris Merchant (University of Reading, formerly of the University of Edinburgh) and funded by NERC and the UK Government. Further documentation is available via the NEODC website:  https://catalogue.ceda.ac.uk/uuid/ff8a7f27b827c108dd9756adffaaa942
Envisat AATSR ARC L2P/L3U  [UPA-L2P_GHRSST/UPA-L3U_GHRSST]

The L2P product contains full resolution dual-view Sea Surface Temperature (SST) values. These SST use the ARC SST retrieval and cloud screening which differ from the methods used to produce the Gridded Surface Temperature (ATS_NR__2P) products. In addition to SST, the L2P products contain the ATSR Saharan Dust Index (ASDI) and the clear-sky probability estimated by the ARC cloud detection algorithm.  The L2P processor also generates L3U products; these are the L2P products averaged onto a regular grid at 0.1 degree resolution (they are therefore similar to the AR / Meteo Envisat-format products).  The L2P and L3U products are provided in NetCDF-4 format following GHRSST Data Specifications (GDS) v2.  The L2P/L3U archive was reprocessed in 2013 with a new processor based upon the ARC SST; the changes are outlined in full in the L2P Reprocessing User Notehttps://earth.esa.int/eogateway/documents/20142/37627/User%20Note%20for%20%28A%29ATSR%20L2P%20Reprocessing
Cloudless True Color Data

Creating monthly cloudless mosaics of images is invaluable for forest management as they provide a consistent and clear view of the forest canopy throughout the year. These mosaics enable forest managers to track seasonal changes, identify potential threats like pest infestations or wildfires, and make informed decisions regarding tree health and growth. Additionally, by having a reliable historical record of forest conditions, these mosaics assist in long-term planning and sustainable resource management. Furthermore, the accessibility and accuracy of monthly cloudless mosaics enhance collaboration among stakeholders, allowing suitable policy development.

Envisat MERIS Reduced Resolution - Level 1 [MER_RR__1P/ME_1_RRG]

The MERIS Level 1 Reduced Resolution (RR) product contains the Top of Atmosphere (TOA) upwelling spectral radiance measures at reduced resolution. The in-band reference irradiances for the 15 MERIS bands are computed by averaging the in-band solar irradiance of each pixel. The in-band solar irradiance of each pixel is computed by integrating the reference solar spectrum with the band-pass of each pixel.  The MERIS RR Level 1 product has Sentinel 3-like format starting from the 4th reprocessing data released to users in July 2020.  Each measurement and annotation data file is in NetCDF 4. The Level 1 product is composed of 22 measurements data files: 15 files containing radiances at each band (one band per file), accompanied by the associated error estimates, and 7 annotation data files.  The band-pass of each pixel is derived from on-ground and in-flight characterisation via an instrument model. The values "Band wavelength" and "Bandwidth" provided in the Manifest file of the Level 1 products are the averaged band-pass of each pixel over the instrument field of view.  The Auxiliary data used are listed in the Manifest file associated to each product.  MERIS was operating continuously on the day side of the Envisat orbit (descending track). RR data was acquired over 43.5 minutes in each orbit, i.e. 80% of the descending track.
