    "time": "2026-09-20 09:00 America/New_York = 13:00:00Z (EDT, UTC-4 on that date), as the request fixes.",
    "place": "NWS/NOAA station KNYC, Central Park, Manhattan, New York City. KNYC was available and reporting; no substitute station was needed.",
    "units": "Tenths of a degree Fahrenheit as an integer, per the request: 72.1 F is 721.",
    "observationSelection": "The observation nearest 13:00:00Z by absolute time difference, counting both routine hourly METARs and SPECIs. That is the 2026-09-20T12:55:00Z SPECI, 5 minutes before the target; the next candidate, 13:14:00Z, is 14 minutes after. The 12:51:00Z routine hourly METAR (9 minutes before) carries the same temperature, so hourly-only selection yields the same answer.",
    "temperatureField": "Air (dry-bulb) temperature, taken at the finest precision the observation reports: the METAR remark T-group T01720167, i.e. 17.2 C. The coarse body group of the same METAR reads 17/17.",
    "conversion": "F = C * 9/5 + 32, applied to 17.2 C => 62.96 F. In tenths of a degree that is 629.6, rounded half-up to the nearest integer => 630. This matches the whole-degree Fahrenheit value of 63.0 F that the Iowa Environmental Mesonet ASOS archive publishes for the same observation."

  "notes": "Panel-evidence brief (evidence: panel), so the fact is off chain and the panel recipe is the only applicable kind; the pinned block window bounds when the answer was fixed, not what was scanned. Primary source: the NWS api.weather.gov observation endpoint for station KNYC (Central Park). I pulled https://api.weather.gov/stations/KNYC/observations?start=2026-09-20T11:00:00Z&end=2026-09-20T15:00:00Z and listed every observation with its offset from 13:00:00Z: 12:18 (17.2 C), 12:41 (17.2), 12:51 (17.2), 12:55 (17.2), 13:14 (17.8), 13:26 (17.2), 13:34 (17.2), 13:40 (17.2), 13:51 (17.2). Nearest is 12:55:00Z at -5 min; its raw METAR is 'KNYC 201255Z AUTO VRB04KT 3SM -RA BR FEW009 BKN014 OVC019 17/17 A3008 RMK AO2 P0000 T01720167', quality control flag V (validated). T0172 = 17.2 C = 62.96 F = 630 tenths. Cross-checked against a second, independent operator: the Iowa Environmental Mesonet ASOS archive (https://mesonet.agron.iastate.edu/cgi-bin/request/asos.py?station=NYC&data=tmpf&data=tmpc&year1=2026&month1=9&day1=20&year2=2026&month2=9&day2=20&tz=UTC) reports station NYC at 2026-09-20 12:55 UTC as tmpf=63.00, tmpc=17.22 - the same observation, same value. I also verified the pinned window on two Ethereum mainnet endpoints from separate operators, https://rpc.flashbots.net/fast and https://ethereum-rpc.publicnode.com: both return eth_chainId 0x1, block 26019859 hash 0xb43a673cd84dd7adfedebddbd21b9c94cbbadb7b5d60c9308d8d6109fae49c73 at 2026-09-20T16:15:47Z, and block 26020158 hash 0x0f0b0919aaa879da43b11cded4198d8fbf51272883ab69e38c64eb2fe787c89b at 2026-09-20T17:15:47Z, matching the brief's toBlockHash exactly. The one judgement call that could split a panel is the 13:14:00Z observation (17.8 C = 64.0 F = 640 tenths); it is 14 minutes after the target against 5 minutes before for 12:55, so nearest-in-time selects 12:55, and the routine hourly ob on either side of the target (12:51 and 13:51) both read 17.2 C, so every reasonable selection except 'first ob at or after the hour' lands on 630."
