+# Jerusalem Air Quality — Weekday vs Shabbat
+
+Twelve months of 5-minute-resolution air-quality readings from **12 monitoring
+stations across Jerusalem**, formatted for analysing the weekday vs Friday vs
+Shabbat (Saturday) pattern in urban pollution.
+
+The motivation: Jerusalem has a uniquely strong weekly traffic cycle — many
+streets in observant neighbourhoods empty out from Friday afternoon to
+Saturday night. This dataset is intended to support quantitative work on
+the resulting air-quality signal.
+
+## Source and attribution
+
+All readings come from the **Israeli Ministry of Environmental Protection
+(המשרד להגנת הסביבה)** national air-quality monitoring network, accessed
+through the public portal at <https://air.sviva.gov.il/>.
+
+The MoEP / sviva.gov.il site is the canonical source. This dataset is a
+convenience repackaging of that public data into a tidy parquet file with
+some derived columns (local time, day-of-week, Shabbat/Friday flags) and
+12 months of history pre-aggregated for the Jerusalem stations.
+
+If you use this data in research or downstream work, please cite the
+**Israeli Ministry of Environmental Protection** as the original source.
+
+## Coverage
+
+- **Window:** 2025-04-28 → 2026-04-28 (12 months, full year)
+- **Resolution:** 5 minutes (native sensor cadence)
+- **Stations:** 12 active continuous monitoring stations within the
+  Jerusalem region (`regionId == 8` in the source system).
+- **Total valid readings:** ~7.1 million (only readings flagged `valid`
+  by the source system are included; sensor-error / calibration rows are
+  dropped).

+## Quick start
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("danielrosehill/Jerusalem-Air-Quality-Shabbat", split="train")
+df = ds.to_pandas()
+
+# Mean NO2 by day of week, for Bar Ilan St
+import pandas as pd
+no2 = df[(df.station_id == 5) & (df.pollutant == "NO2")]
+print(no2.groupby("dow")["value"].mean())
+```
+
+Or directly with pandas / pyarrow:
+
+```python
+import pandas as pd
+df = pd.read_parquet("hf://datasets/danielrosehill/Jerusalem-Air-Quality-Shabbat/data/readings.parquet")
+```
+
+## Headline finding (preliminary)
+
+Using the daytime window 07:00–22:00 local time, **gaseous traffic
+pollutants drop sharply on Shabbat across all 12 stations**, with Friday
+sitting roughly half-way:
+
+| Pollutant | Friday % drop vs Sun-Thu | Shabbat % drop vs Sun-Thu |
+|---|---|---|
+| NO    | ~40 % | ~55 % (range 19–76 %) |
+| NOx   | ~34 % | ~52 % |
+| NO₂   | ~30 % | ~47 % |
+| Toluene | ~44 % | ~38 % |
+| Benzene | ~25 % | ~21 % |
+| CO    | ~7 %  | ~8 %  |
+
+The biggest Shabbat drops are in observant West-Jerusalem
+neighbourhoods (Bezalel ~73 %, Bar Ilan ~55 %, Romema ~52 %) and the
+smallest along corridors that carry significant non-observant traffic
+(Rockefeller Museum ~13 %, Safra Square ~33 %).
+
+**Particulates (PM2.5, PM10) do _not_ drop on Shabbat — they often rise.**
+This is a real signal in the data but is confounded by Saharan dust
+intrusions and weekend grilling, and needs its own controlled analysis.
+
+Per-station summary tables are in `analysis/`. Full write-up of the
+methodology, caveats, and limitations is in `analysis/FINDINGS.md`.
+
+## Caveats and known limitations
+
+- **Shabbat is approximated as the calendar Saturday in local time.** Real
+  Shabbat onset/conclusion is sunset-based and varies between roughly
+  16:30 and 19:30 across the year. A Hebcal-driven exact window would
+  tighten the signal, especially for the Friday-evening / Saturday-night
+  transitions.
+- **Jewish holidays are _not_ excluded.** The window 2025-04 → 2026-04
+  contains Pesach, Shavuot, the High Holy Days, Sukkot, Hanukkah and
+  Purim. Yom Kippur in particular is the cleanest air day of the year
+  nationally and biases any "weekday" baseline that includes it
+  (Wed 2025-10-01 was YK 2025).
+- **Sensor validity flag is trusted as-is.** Only `valid: true` readings
+  are included; the source system's QC decisions have not been
+  re-verified.
+- **Two stations have partial coverage**: 623 (Atarot Eden) starts
+  2025-08-06; 635 (Bezalel St) starts 2026-02-05. Their statistics use
+  fewer Saturdays.
+- **Station 509** (Malchei Israel) is listed as active in the source
+  metadata but returned no historical data over this window and is
+  omitted from `data/readings.parquet`.
+- **Region filter:** stations were selected by `regionId == 8` in the
+  source system. Two stations on the periphery of the region (Highway 16
+  and Atarot) sit outside the historical city core but are functionally
+  part of the Jerusalem network.
+
+## License
+
+The underlying data is published by the Israeli Ministry of Environmental
+Protection as a public-information service. This dataset is shared under
+**CC-BY-4.0** with attribution to the Ministry as the original data
+source.
+
+## Versioning
+
+- **v1** (2026-04-28): initial release. 12 months × 5-min × 12 stations,
+  long-form parquet.

+# Jerusalem Air Quality — Weekday vs Friday vs Shabbat (preliminary)
+
+12 months of 5-minute resolution data (2025-04-28 → 2026-04-28) for 12 active
+Israeli MoEP / Envista ARM stations in Jerusalem, pulled from
+`https://air-papi.sviva.gov.il/v1/envista/...` (see
+`research/api-air-sviva-gov-il.md`).
+
+Daytime window = 07:00–22:00 local (Asia/Jerusalem). Friday evening through
+Saturday morning is collapsed into "Sat" since Shabbat-observant traffic is
+already off the road by then; this slightly understates the true Shabbat drop
+because it includes Friday morning rush in "Fri".
+
+Each station has ~50 Fridays and ~50 Saturdays in the window (station 623
+joined Aug 2025, station 635 joined Feb 2026 — small samples flagged).
+
+## Signal: traffic-derived gases drop sharply on Shabbat
+
+Median Shabbat % drop vs Sun-Thu daytime mean, across the 12 stations:
+
+| Pollutant | Friday % drop | Shabbat % drop |
+|---|---|---|
+| NO    | ~40 % | ~55 % |
+| NOx   | ~34 % | ~52 % |
+| NO₂   | ~30 % | ~47 % |
+| Toluene | ~44 % | ~38 % |
+| Benzene | ~25 % | ~21 % |
+| CO    | ~7 %  | ~8 %  |
+
+The signal is consistent, monotonic (Sun-Thu > Fri > Sat for every gaseous
+traffic pollutant at every station except a couple of edge cases), and
+strongest in the most observant neighbourhoods.
+
+## Where the drop is biggest
+
+Top stations by NOx Shabbat drop:
+
+| Station ID | Location | NOx weekday | NOx Shabbat | % drop |
+|---|---|---|---|---|
+| 635 | Bezalel St (city centre, near Geula) | 34.0 | 9.0 | **73 %** |
+| 310 | Central Bus Station Platform 10 | 130.0 | 40.5 | **69 %** |
+| 458 | Devorah HaNevia St (residential) | 39.6 | 15.5 | **61 %** |
+| 328 | Atarot industrial zone | 38.8 | 15.8 | **59 %** |
+| 547 | Highway 16 / Beit interchange | 18.1 | 7.8 | **57 %** |
+| 5   | Bar Ilan St (arterial) | 26.4 | 11.9 | **55 %** |
+| 193 | Romema (ultra-Orthodox) | 14.3 | 6.8 | **52 %** |
+| 607 | Beit Safafa | 18.6 | 9.3 | **50 %** |
+| 13  | Baka (residential mixed) | 13.9 | 8.5 | **39 %** |
+| 36  | Safra Square (city centre) | 11.1 | 7.5 | **33 %** |
+| 623 | Atarot Eden (8 mo. only) | 12.1 | 9.1 | **25 %** |
+| 568 | Rockefeller Museum | 33.1 | 28.7 | **13 %** |
+
+Rockefeller Museum (568) is the surprise outlier — much smaller drop than
+neighbours. Worth checking whether the inlet sits next to a road that
+remains busy on Shabbat (Sultan Suleiman / Salah a-Din area carries a lot
+of East-Jerusalem traffic, which doesn't observe Shabbat).
+
+Conversely, the very tight grouping at 50–70 % drops in West-Jerusalem
+arterial / residential stations is a strong correlate of the population's
+observance of vehicular Shabbat.
+
+## Friday is genuinely intermediate
+
+Friday daytime sits roughly **half-way** between weekday and Shabbat for
+NOx at most stations — consistent with reduced commercial activity but
+ongoing pre-Shabbat shopping/errands until early afternoon.
+`scripts/shabbat_correlation.py` also writes `station-{id}-friday-split.csv`
+breaking Friday into AM (07–13) and PM (14–22) — the AM block looks like a
+near-normal weekday; the drop concentrates in PM.
+
+## PM2.5 / PM10 do **not** drop on Shabbat — they often rise
+
+Particulate matter increases on Saturdays at almost every station (-30 % to
+-65 % "drops", i.e. Sat is *higher* than weekday). Several plausible
+contributors, none ruled out yet:
+
+- April–May 2026 included multiple Saharan dust intrusions; 12 months is
+  not enough to wash that out and Saturdays happened to coincide with some
+  of them.
+- Charcoal grilling (mangal) is a well-documented Israeli Friday-afternoon
+  / Saturday source of PM2.5 and PM10.
+- Reduced wind / different boundary-layer dynamics on weekends.
+
+This is a real finding for the project but it cuts the other way from the
+gaseous traffic story and deserves its own analysis (probably needs to
+controlling for synoptic dust days).
+
+## Caveats
+
+- Daytime defined as 07–22 ignores the actual Shabbat onset/conclusion
+  times, which vary 17:00–19:00 by season. A Hebcal-driven exact window
+  would tighten the signal.
+- Calendar holidays (Pesach 2025-04, Shavuot, Rosh Hashana, Yom Kippur,
+  Sukkot, Hanukkah) are not excluded — Yom Kippur in particular is the
+  cleanest air day of the year nationwide and inflates "weekday" cleanness
+  for any year that includes it (Wed 2025-10-01 was YK 2025).
+- 12 months × 5-min data is ~700k rows per station, ~2 GB total raw JSON;
+  the raw is gitignored and regenerable via the API; only summary CSVs are
+  committed.
+
+## How to reproduce
+
+```bash
+# 1. Pull raw data (mints Guest tokens, ~2 GB)
+.venv/bin/python -m pip install pandas numpy   # one-off
+bash scripts/fetch_historical.sh               # (TODO: lift the inline pull from session)
+
+# 2. Run analysis
+.venv/bin/python scripts/shabbat_correlation.py
+# → writes analysis/headline-3way.csv + per-station CSVs
