Searchable fields

This reference documents 537 filter names and 539 selectable output names for Search. Counts include public aliases; compatibility identifiers remain accepted separately. Internal-only fields and internal parcel IDs cannot be Search filters or selected outputs. Enrich-only calculations cannot be filters or selected through fields. Set enrich: true to return all Enrich fields separately in each match’s enrichment. That object includes catalog geometry and identifiers; shortlist geometry is opt-in. Put a scalar name in filters to require a value; put any listed name in fields to request additional information without filtering. Every filter is required (AND). Text/booleans support eq, ne, in; numbers also support lt, lte, gt, gte, and inclusive between. Null never satisfies a hard filter. The special geometry filter supports intersects and within with WGS84 GeoJSON Polygon/MultiPolygon values. Intersects includes boundary touches; within requires the entire parcel to be covered by the area, including its boundary. Geometry filters do not automatically return geometry. See the Search endpoint for validation limits. Stored dates use YYYY-MM-DD; timestamps use UTC ISO 8601 and also support ordered comparisons. The loaded parcel schema is checked at runtime and determines their types. Use JSON numbers and booleans, not strings containing numbers or true/false. city means case-insensitive situs scity; census_subdivision selects the Census subdivision. fema_flood_zone uses Fetch; parcel_fema_flood_zone selects the stored parcel attribute. Every request must include state or state2 with eq and one two-letter US state or DC code, or in and a nonempty list of codes. A negative-only state filter does not satisfy this requirement. county is optional and accepts a five-digit FIPS string or a normalized county name. Calculations use the existing Fetch producers and their source budgets. Configured live sources may be used. Eligibility does not guarantee local data availability or coverage; inspect field_status and response completion status. Point fields describe the interior analysis point. Whole-parcel fields use the original parcel boundary. The geometry filter constrains where parcels are found.

Blank for lead/SO2/NO2 (which EPA never classifies) and for maintenance-only points — this field collects classifications from NONATTAINMENT matches only, so a point whose classified areas are all Maintenance reads blank here even though those areas carry a published classification. For a single pollutant’s own classification (not this cross-pollutant max), and for maintenance classifications, use air_quality_<pollutant>_classification instead (e.g. air_quality_ozone_classification, air_quality_pm25_classification).
`annual_precipitation_normal_mm`	float	mm	Mean annual total precipitation, expressed as liquid-equivalent depth in mm, from NOAA NCEI nClimGrid 1991–2020 climate normals on a 1/24-degree grid (~4.6 km north–south). CONUS only.

`btm_gas_candidacy_flag`	bool	—	DERIVED knockout screen for on-site (behind-the-meter) gas-generation candidacy: an EIA interstate gas pipeline within 10 km (formula v2, distance-only; v1’s shale-play conjunct was dropped — shale membership gates wellhead gas, not transported gas). NOT a deliverability claim. Derived; MEDIUM confidence.
`cdl_class`	string	—	USDA Cropland Data Layer class name at the queried point — a crop (Corn, Soybeans, Cotton, Winter Wheat, …) OR a non-crop CDL land-cover class (Developed, Open Water, Deciduous Forest, Grassland/Pasture, …). NULL only when the point is outside the CDL CONUS grid or on a background/nodata cell. Pair with is_cultivated to distinguish cultivated cropland from non-crop cover.
`clear_sky_ratio_ghi_annual`	float	—	Annual clear-sky ratio for GHI (ΣGHI/ΣClearsky GHI, 0-1) from one NREL NSRDB GOES-TMY year — the fraction of the theoretical clear-sky global irradiance actually realized once clouds and aerosols are accounted for.
`clearsky_dni_annual_kwh_m2_day`	float	kWh/m2/day	Annual clear-sky direct normal irradiance sum (kWh/m2/day) from one NREL NSRDB GOES-TMY year — the theoretical maximum beam irradiance absent clouds and aerosols.
`clearsky_ghi_annual_kwh_m2_day`	float	kWh/m2/day	Annual clear-sky (cloud-free-modeled) global horizontal irradiance sum (kWh/m2/day) from one NREL NSRDB GOES-TMY year — the theoretical maximum GHI absent clouds and aerosols.
`coast_distance_m`	float	meters	Geodesic distance from the queried point to the nearest point on the nearest NOAA CUSP shoreline feature (measured to the SEGMENT, not to a vertex). CUSP charts every tidal shoreline it maps — open coast, bays and estuaries, the full tidal reach of rivers, and harbour structures such as bulkheads, wharves and breakwaters — so this is distance to NOAA-mapped SHORELINE, not distance to open ocean. A tidal-river waterfront therefore reads metres while the open sea is a hundred kilometres away: Philadelphia reads ~13 m against ~89 km of open sea, and the Anacostia in DC reads a few hundred metres against ~163 km. The value is only large where no CUSP feature is near at all (interior states). A small value therefore does NOT establish marine exposure on its own, and cannot carry a storm-surge inference until the matched shoreline is independently confirmed to be marine — stated here as well as in the interpretation hints, because the public field-catalog table renders descriptions only. Channelized inland water (Man-made.Canal*, Man-made.Lock) is excluded. Always populated.
`coastal_high_hazard`	bool	—	True if the FEMA flood zone is V-family (V/VE/V1-30) — a coastal high-hazard area subject to high-velocity wave action (breaking waves >= 3 ft).

`days_with_min_temp_below_0c_annual_avg`	float	days/year	Mean annual count of days in 1991–2020 whose modeled daily Tmin was strictly below 0.00°C after NOAA’s 0.01°C rounding, from the roughly 3–5 km nClimGrid-Daily grid. Float annual average; CONUS land only.
`design_wet_bulb_temperature_0_4pct_degc`	float	degC	TMY-based approximation of the 0.4% cooling design wet-bulb: the 99.6th percentile of hourly wet-bulb over one NREL NSRDB GOES-TMY year, solved psychrometrically from dry-bulb + dew-point. A single typical year clips extremes, so this runs slightly cool of the true multi-year ASHRAE design value (reported at medium confidence).
`design_wind_speed_mph`	float	mph	ASCE 7-22 basic design wind speed (3-second gust, Risk Category II / 700-yr MRI, Exposure C) from NOAA’s free CC0 mirror of the ASCE wind vectors.

`dni_clear_sky_ratio_annual`	float	—	Annual clear-sky ratio for DNI (ΣDNI/ΣClearsky DNI, 0-1) from one NREL NSRDB GOES-TMY year — the fraction of the theoretical clear-sky beam irradiance actually realized.
`documented_orphaned_wells_within_1km_count`	int	—	Exact count of documented unplugged orphaned oil and gas wells within 1 km of the queried point, from the USGS DOW dataset. A 0 and a null mean different things — null means the state has no inventory in this dataset at all.
`domestic_well_household_density_class`	string	—	Coarse class over the same modelled self-supplied-household density — none / sparse / moderate / dense / very_dense. Frozen physical bands, not quantiles.
`domestic_well_households_per_km2`	float	households/km2	Modelled self-supplied (private-well) households per km², averaged over the 3 km × 3 km neighbourhood containing the point.

`easement_acres_on_parcel`	float	acres	Absolute acres of PAD-US conservation easement area intersecting the matched parcel’s own boundary — the parcel-clipped encumbered acreage, computed in the parcel’s local UTM (equal-area) projection. NOT the whole mapped easement polygon’s size (see easement_acres for that).
`easement_fraction_of_parcel`	float	—	Fraction (0.0-1.0) of the matched parcel’s own boundary encumbered by PAD-US conservation easement polygons — the parcel share, computed by intersecting easements with the parcel boundary in the parcel’s local UTM (equal-area) projection. NOT the whole mapped easement polygon’s size (see easement_acres for that).
`easement_holder`	string	—	Holder organization of the intersecting conservation easement.
`easement_purpose`	string	—	Stated purpose of the intersecting easement. PAD-US 4.1 publishes no stated-purpose attribute for easement records, so this is null (semantic absence) even when an easement is present.
`easement_type`	string	—	Type/category of the intersecting PAD-US conservation easement.
`easement_year_established`	int	—	Year the intersecting PAD-US conservation easement was established.

`no2_1hr_monitor_aqs_site_id`	string	—	EPA AQS Site ID of the monitor that supplied no2_1hr_design_value_ppb, in the SS-CCC-NNNN printed form. Identifies which physical monitor the value came from, not the queried coordinate itself.

`open_ocean_distance_m`	float	meters	Geodesic distance to the OPEN SEA, where open sea means the water still connected to the deep ocean once every entrance narrower than 20 km is sealed - that is, what lies outside the continental landmass. Bays, sounds, estuaries and tidal rivers are INSIDE that boundary, not part of it, so Baltimore Inner Harbor reads about 139 km and Philadelphia about 90 km even though both sit on tidal water. Points on the outer coast read metres (Santa Monica 40 m, Virginia Beach 450 m, Galveston 890 m). This is NOT the same question as coast_distance_m, which measures to the nearest tidal shoreline of any kind and is the right field for river frontage, port access or tidal exposure; at a bay head the two differ by 100 km or more and both are correct. Returns 0 for a point already in open water, and a large distance rather than a null for an inland point (about 1,365 km in Denver). Great Lakes shoreline is not open sea under this definition and is excluded by construction, since the source ocean polygon contains no lakes. Coverage is the US and its offshore approaches, not the whole coordinate envelope: the open-sea polygon is derived over five processing domains covering about 69 percent of the accepted envelope, and every US shoreline sits inside them (asserted at build time). Outside them - the open North Pacific west of 135W below 46N, and north of 56N - the field is ABSENT rather than a number, because out there the polygon’s nearest edge is where a processing box clipped the geometry rather than a coastline, and a distance to that edge would be fiction. No US site is affected.
