Showing 1,154 of 1,154 records. = gap-filled data

This table shows raw (unsmoothed) monthly anomalies. The spiral applies a 12-month moving average to highlight long-term trends.

Methodology

Methodology How we calculate anomalies

1. Data Acquisition

We use NOAA's nClimGrid dataset, which provides homogenized temperature data on a 5km grid, for the nearest grid point with historical coverage starting from 1930.

Temperature metric: Monthly average temperature (TAVG). When TAVG is unavailable, we use (TMAX + TMIN) / 2 as a proxy.

2. Gap Filling

Some months may have missing data. We fill gaps using data from nearby weather stations (within ~200km).

Initial gaps

Filled

Unfillable

3. Baseline Calculation

The baseline is a 25-year window dynamically centered on the data's midpoint, requiring at least 90% coverage. If coverage is insufficient, the window shifts forward in 5-year increments until the threshold is met.

Period: 1966 – 1991 (100% coverage)

Month	Baseline	Years
January	53.6°F	26/26
February	55.5°F	26/26
March	56.7°F	26/26
April	59.9°F	26/26
May	64.2°F	26/26
June	69.1°F	26/26
July	74.9°F	26/26
August	75.2°F	26/26
September	72.8°F	26/26
October	66.5°F	26/26
November	59.2°F	26/26
December	53.6°F	26/26

4. Anomaly Calculation

For each month, we calculate how far it deviates from the baseline. These are raw monthly anomalies.

Anomaly = Actual Temperature − Baseline[month]

5. Smoothing

The spiral visualization applies a 12-month centered moving average to reduce month-to-month noise and highlight multi-year warming trends. The spiral shows smoothed values, not raw anomalies.

6. Reading the Visualizations

Spiral: A 3D helix where each loop represents one year. The radius indicates the smoothed temperature anomaly, and colors range from blue (cold) to red (warm). The top view shows the annual cycle, while the side view shows time progression.

Stripes: Each stripe represents one year's average anomaly (the mean of all monthly anomalies for that year). No additional smoothing is applied; yearly aggregation naturally reduces noise.

Color scale: Color bounds are set to the 5th and 95th percentile of anomalies to avoid outlier washout, with a neutral zone of approximately ±0.1°C.

Frequently Asked Questions

Is Altadena, California getting warmer?

Based on 96+ years of NOAA temperature records, Altadena has warmed at a rate of approximately 0.50°F per decade. This trend is calculated from monthly temperature anomalies relative to the location's historical baseline period.

What was the warmest year on record in Altadena?

The warmest year on record in Altadena was 2014, based on average annual temperature anomaly from NOAA station data.

Where does the temperature data for Altadena come from?

Data comes from the nClimGrid 5km Grid Point weather station, part of NOAA's Global Historical Climatology Network. This station has recorded 96+ years of temperature observations used to build Altadena's climate profile.

How are the climate visualizations for Altadena created?

Three visualizations are generated from Altadena's NOAA data: a climate spiral showing monthly temperature anomalies as concentric rings (inspired by NASA), warming stripes where each vertical stripe represents one year's temperature anomaly, and a linear trend chart showing the long-term trajectory.

Can I download Altadena's temperature data?

Yes. The interactive data table on this page shows every monthly temperature reading in Altadena's record. You can filter by decade and download the complete dataset as a CSV file for your own analysis.
