Sites¶

NEON operates 81 field sites (terrestrial and aquatic, CORE and GRADIENT) in 20 ecoclimatic domains D01–D20². Sites have four-letter codes (HARV is Harvard Forest). Tools: neon_search_sites and neon_get_site.

Searching¶

Served from a cached site catalog (about 0.6 MB over GraphQL instead of the 27 MB REST list). Filters combine:

• query — code, name words, state or domain names ("Harvard", "Alaska");
• domain_code, state_code (two letters), site_type (CORE or GRADIENT);
• product — only sites with data for that product (code or name);
• latitude + longitude (+ radius_km, default 100) — nearest first, each result with distanceKm;
• include_elevation — adds elevation and UTM coordinates from one extra cached request (/locations/sites, 2.7 MB upstream).

One site¶

neon_get_site accepts a code or a name and returns the site record plus, by default, every data product available there with its month ranges and the number of provisional months¹. Other sections: releases, description (the full text; summaries are clipped), location (elevation, UTM, location properties, active periods) or all. Filter the product list with products_query and page it with products_offset.

Pitfalls¶

• Some locations of type SITE are not field sites (headquarters, mobile deployment platforms); neon_search_sites covers only the 81 field sites.
• A misspelled or partial name that fits several sites returns ambiguous_input; similar-looking names do not resolve silently ("Blue Ridge" is not "Blue River").
