Sentinel-2 reflectance 3-month mosaics, years 2022 onwards

Sentinel-2 satellite image mosaics are produced from data provided by MultiSpectral Instruments (MSI) onboard Sentinel-2 satellites. These mosaics covering years 2017 - 2021 have been produced using the current version of Sentinel-2 Global Mosaic-service (https://s2gm.land.copernicus.eu/mosaic-hub) of Copernicus program of European Union. The image acquisition period yearly mosaics have been from the mid-June to the mid-August. The value of pixel of the individual bands is the estimate of ground reflectance, multiplied by coefficient 10000. The RGB-images (bands B08, B04, B03) have been scaled to 8-bit in order to make visualization easier. The value of meta-mosaic is the number of day from the start of year of selected pixel. Pixel size of all mosaics is 10 m. Original Sentinel data CLMS / ESA, mosaic processing by S2GM-service with postprocessing by SYKE. Coordinate system: ETRS-TM35FIN.
Sentinel-2 monthly index mosaics: NDVI, NDBI, NDMI, NDSI, NDTI (FMI Tuulituhohaukka)

Sentinel-2 monthly index mosaics: NDVI, NDBI, NDMI, NDSI, NDTI. Scale: 10m. Available each year for April-October. Original Sentinel-2 data from ESA Copernicus Sentinel Program, processing by SYKE and FMI. Coordinate system: ETRS-TM35FIN.
Sentinel-2 annual surface reflectance mosaics (FMI Tuulituhohaukka)

Sentinel-2 annual surface reflectance  mosaics. Scale: 10m. Original Sentinel-2 data from ESA Copernicus Sentinel Program, mosaic processing by Sentinel-2 Global Mosaic Service, mosaic postprocessing by SYKE. Coordinate system: ETRS-TM35FIN.
Landsat (4 and 5) yearly index mosaics: NDVI, NDBI, NDMI, NDSI, NDTI (FMI Tuulituhohaukka)

Landsat (4 and 5) yearly index mosaics: NDVI, NDBI, NDMI, NDSI, NDTI. Scale: 30m. Available for the years 1984-2011. Landsat-4/5 imagery from United States Geological Survey. Mosaics processed by SYKE at Finnish National Satellite Data Centre. Coordinate system: ETRS-TM35FIN.
Harmonized Landsat-5/7 satellite image mosaic timeseries

Harmonized dataset of yearly satellite image mosaics (reflectance of bands and image indices NDVI, NDMI, NDTI, NDWI) based on Landsat-5/7 imagery and starting from year 1984 and ending year 2014. The image acquisition period of individual year has been from start of May to end of September at Southern Finland and shorter in Northern Finland. Provided bands are B1: blue, B2: green, B3: red, B4: NIR, B5: SWIR1, B7: SWIR2, image indices NDMI: Normalized Difference Moisture Index, NDTI: Normalized Difference Tillage Index, NDVI: Normalized Difference Vegetation Index, NDWI: Normalized Difference Water Index and other mosaics META: The pixel value is the number of day of selected observation, NUMOBS: The pixel value is the number of available valid observations. Pixel size is 20 m. Original Landsat data USGS Landsat Level-2 Collection-2, mosaic processing by SYKE and archiving at FMI/NSDC (https://nsdc.fmi.fi/). Coordinate system: ETRS-TM35FIN.
Harmonized Corine Land Cover (AquaInfra)

The Harmonized Corine Land Cover is meant for change detection and is calculated from national Corine land cover products 2000, 2006, 2012 and 2018. All years have same classification with 46 classes according to Corine 2018. The files were converted into cloud optimized Geotiffs to allow more convenient access to the data by the analysis tools developed for the AquaINFRA project. Pixel size 20m. Coordinate system: EPSG:3067
Harmonized Landsat-8/9 satellite image mosaic timeseries

Harmonized dataset of yearly satellite image mosaics (reflectance of bands and image indices NDVI, NDMI, NDTI, NDWI) based on Landsat-8/9 imagery and starting from year 2013 and currently ending year 2024. The image acquisition period of individual year has been from start of May to end of September at Southern Finland and shorter in Northern Finland. Provided bands are B1: Coastal, B2: blue, B3: green, B4: red, B5: NIR, B6: SWIR1, B7: SWIR2, image indices NDMI: Normalized Difference Moisture Index, NDTI: Normalized Difference Tillage Index, NDVI: Normalized Difference Vegetation Index, NDWI: Normalized Difference Water Index, and other mosaics META: The pixel value is the number of day of selected observation, NUMOBS: The pixel value is the number of available valid observations. Pixel size is 20 m. Original Landsat data USGS Landsat Level-2 Collection-2, mosaic processing by SYKE and archiving at FMI/NSDC (https://nsdc.fmi.fi/). Coordinate system: ETRS-TM35FIN.
Sentinel-1 11-days backscatter mosaics: VV and VH polarisation (FMI Tuulituhohaukka)

Sentinel-1 11-days backscatter mosaics: VV and VH polarisation. Scale: 20m. Original Sentinel-1 data from ESA Copernicus Sentinel Program, processing by FMI. Coordinate system: ETRS-TM35FIN.
Sentinel-2 11-days surface reflectance mosaics (FMI Tuulituhohaukka)

Sentinel-2 11-days surface reflectance mosaics. Scale: 20m. Original Sentinel-2 data from ESA Copernicus Sentinel Program, mosaic processing by Sentinel-2 Global Mosaic Service. Mosaic postprocessing by SYKE. Coordinate system: ETRS-TM35FIN.
Sentinel-2 reflectance 3-month mosaics, years 2017-2021

Sentinel-2 satellite image mosaics are produced from data provided by MultiSpectral Instruments (MSI) onboard Sentinel-2 satellites. These mosaics covering years 2017 - 2021 have been produced using the first version of Sentinel-2 Global Mosaic-service (https://s2gm.land.copernicus.eu/mosaic-hub) of Copernicus program of European Union. The image acquisition period for summer mosaics have been from the start of July to the end of September. There are also spring mosaics available for some years, their image acquisition period has been from the start of April to the end of June. The value of pixel of the individual bands is the estimate of ground reflectance, multiplied by coefficient 10000. The RGB-images (bands B08, B04, B03) have been scaled to 8-bit in order to make visualization easier. Pixel size of all mosaics is 10 m. The holes due to cloud masking have been interpolated and the mask_nodata-mosaic indicates these pixels. Original Sentinel data CLMS / ESA, mosaic processing by S2GM-service with postprocessing by SYKE. Coordinate system: ETRS-TM35FIN.
