PhenoCam Site Metadata File Format

Site metadata are provided in two formats. The first is a simple text file with colon separated key-value pairs. The file is named using the convention <sitename>_meta.txt. An example text format metadata files is shown below:

    PhenoCam Fair Use Data Policy: Since its inception, the objective
    of the PhenoCam network has been to serve as a repository for
    phenologically-relevant, digital, repeat (time-lapse) imagery, and
    to make that imagery, and derived data products, freely available
    to a wide array of third-party data end-users, including
    researchers, educators, and the general public. Thus, imagery from
    the PhenoCam archive is made publicly available, without
    restriction, for non-commercial scientific and educational
    purposes, and we encourage you to download imagery and datasets
    for use in your own research and teaching.  We request that all
    publications using the dataset (1) properly cite the PhenoCam
    dataset, the associated data descriptor, and other relevant
    publications; and (2) include both a general acknowledgement for
    the PhenoCam project and the appropriate site-specific
    acknowledgements for every site used in your analysis. The text
    for these acknowledgments is included in the metadata file
    associated with each PhenoCam site.  Distribution and Re-use
    Policy: The PhenoCam Dataset version 1.0 is distributed under a
    Creative Commons Attribution-NonCommercial-ShareAlike 4.0
    International License.  Acknowledgments: The development of
    PhenoCam has been supported by the Northeastern States Research
    Cooperative, NSF’s Macrosystems Biology program (award
    EF-1065029), DOE’s Regional and Global Climate Modeling program
    (award DE-SC0016011), and the US National Park Service Inventory
    and Monitoring Program and the USA National Phenology Network
    (grant number G10AP00129 from the United States Geological
    Survey). PhenoCam collaborators, including site PIs and
    technicians, are thanked for their efforts in support of PhenoCam.

Most of the site metadata is provided by the site's local contacts. If you have questions about the metadata for a site we encourage you to contact them, as they are the best source of information about the data from their site.

Some of the metadata values provided have been derived by using gridded datasets and the site location information. These data are provided merely as a convenience and to provide approximate (and consistently-sourced) information on landcover, ecoregion, meteorology, and climate. These data will depend on the accuracy of the site location and the grid size of the source data sets used. Notes on the sources of these data are given below.

EPA Level I Ecoregions:

The ecoregion metadata value refers to the EPA North America Level I Ecoregion.

References:

The key for the ecoregion is as follows:

    
     0: Water
     1: Arctic Cordillera
     2: Tundra
     3: Taiga
     4: Hudson Plain
     5: Northern Forests
     6: Northwestern Forested Mountains
     7: Marine West Coast Forest
     8: Eastern Temperate Forests
     9: Great Plains
     10: North American Deserts
     11: Mediterranean California
     12: Southern Semi-Arid Highlands
     13: Temperate Sierras
     14: Tropical Dry Forests
     15: Tropical Wet Forest
    
  

Köppen-Geiger Climate Classification:

The koeppen-geiger metadata value refers to the Köppen-Geiger present-day climate classification.

The key to the climate classifications is as follows:

    
     Af - Tropical-Rainforest
     Am - Tropical-Monsoon
     As - Tropical-Dry Summer
     Aw - Tropical-Savanna
     BWk - Cold Desert

DAYMET:

The MAT_daymet and MAP_daymet metadata values are the mean annual temperature (MAT) and mean annual precipitation (MAP) values calculated from DAYMET data provided by the ORNL DAAC. The DAYMET dataset is limited to North America, Hawaii, and Puerto Rico. The means were calculated using the 1980-2010 data.

References:

WorldCLIM:

Because the DAYMET data are not global we also provide MAT_worldclim and MAP_worldclim values based on WorldClim dataset.

References:

IGBP Landcover Classification:

The landcover_igbp value is derived using the gridded MODIS landcover data from the Global Land Cover Facility at University of Maryland.

References:

Here are the standard IGBP landcover classes:

    
     0 - Water
     1 - Evergreen Needleleaf forest
     2 - Evergreen Broadleaf forest
     3 - Deciduous Needleleaf forest
     4 - Deciduous Broadleaf forest
     5 - Mixed forest
     6 - Closed shrublands
     7 - Open shrublands
     8 - Woody savannas
     9 - Savannas
     10 - Grasslands
     11 - Permanent wetlands
     12 - Croplands
     13 - Urban and built-up
     14 - Cropland/Natural vegetation mosaic
     15 - Snow and ice
     16 - Barren or sparsely vegetated
     254 - Unclassified
     255 - Fill Value
    
  

WWF Biomes:

The wwf_biome metadata value is derived using the site location and a shapefile of the Terrestrial Ecosystems of the World provided by the World Wildlife Fund (WWF).

References:

The values for wwf_biome are show below:

    
      1 - Tropical and subtropical moist broadleaf forests
      2 - Tropical and subtropical dry broadleaf forests
      3 - Tropical and subtropical coniferous forests
      4 - Temperate broadleaf and mixed forests
      5 - Temperate coniferous forests
      6 - Boreal forests/taiga
      7 - Tropical and subtropical grasslands, savannas, and shrublands
      8 - Temperate grasslands, savannas, and shrublands
      9 - Flooded grasslands and savannas
      10 - Montane grasslands and shrublands
      11- Tundra
      12 - Mediterranean forests, woodlands and scrub or sclerophyll forests
      13 - Deserts and xeric shrublands
      14 - Mangrove
