About
A desk of published measurements.
Instrument Record is a stand-alone observational site. Each category is one question: how do the thermometers compare, where is CO₂, what are the two sea-level instruments doing, is this year’s ice cycle running low, where is the Sun, and how thin is the Holocene on the official clock.
How to read it
- Measurements first. Model output is not ingested here.
- Geological and Holocene context sit next to the satellite era.
- Product disagreement is drawn, not averaged away: UAH, RSS, HadCRUT, GISS.
- Smoothing and reference periods are controls. Native zeros differ; say so.
- Raw and smoothed traces are always one click apart.
What is on the desk
Temperature products, Mauna Loa and Law Dome CO₂, ocean/Niño, sea-level instrument classes, sea ice and snow, the solar cycle, the ICS timescale, and ice-core paleoclimate — plus the methods that make those plots comparable.
On interpretation
The charts do not argue a single attribution. They keep the comparisons inspectable, label schematic series as schematic, and use published observational files (UAH, RSS, HadCRUT5, GISTEMP, NOAA GML, SILSO, NSIDC, Rutgers, CPC ONI, ICS, ice-core compilations) wherever they were reachable.
