How to download NOAA AVHRR 1 km resolution sea surface temperature data?

I need a SST 1 km image of the coast of Netherlands with at least 20 % valid pixels.

After searching and searching I find the NEODAAS portal: http://www.neodaas.ac.uk

I find this image: http://www.neodaas.ac.uk/data/browse/file_info.php?image=AVHRR/uk/2017/04/09/09apr170324uksstp.gif

However I cannot figure out how to actually download the image in SST values? Any suggestions? Or maybe a suggestion for another way of acquiring the image?

Navigate to Dataset Discovery

The 4 km Advanced Very High Resolution Radiometer (AVHRR) Pathfinder Version 5 sea surface temperature (SST) dataset is a reanalysis of historical AVHRR data that have been improved using extensive calibration, validation and other information to yield a consistent research quality time series for global climate studies.

Also, for other dataset you could navigate to Advanced Very High Resolution Radiometer (AVHRR)

enter image description here

The Advanced Very High Resolution Radiometer (AVHRR) provides four- to six-band multispectral data from the NOAA polar-orbiting satellite series. There is fairly continuous global coverage since June 1979, with morning and afternoon acquisitions available. The resolution is 1.1 kilometer at nadir.

For the Vegetation Index: AVHRR Normalized Difference Vegetation Index (NDVI) Composites

Normalized Difference Vegetation Index (NDVI) Composites are produced from multiple Advanced Very High Resolution Radiometer (AVHRR) daily observations that have been composited together to create a nearly cloud-free image showing maximum greenness. An NDVI ratio is produced from bands one and two of the AVHRR composite to produce a derived NDVI band composite.

For the Land Cover Global Land Cover Characterization (GLCC)

Global Land Cover Characterization (GLCC) is a series of global land cover classification datasets that are based primarily on the unsupervised classification of 1-km AVHRR (Advanced Very High Resolution Radiometer) 10-day NDVI (Normalized Difference Vegetation Index ) composites. The AVHRR source imagery dates from April 1992 through March 1993. Ancillary data sources included digital elevation data, ecoregions interpretation, and country- or regional-level vegetation and land cover maps.

  • I need the sea surface temperature download, not NDVI or CLCC... – dtanon Nov 16 '17 at 13:39
  • I've updated my response to a link to the dataset. – whyzar Nov 16 '17 at 13:49
  • thx, however I only see 4 km resolution.. I see the 1 km resolution being used in a lot of literature, I just can't find it.. – dtanon Nov 16 '17 at 13:57
