Solar Irradiance: Four-Chart Comparison

Modern reconstruction, Lean 2015, CMIP5 baseline, and SATIRE-T2 plus Kopp/LASP extension

This page combines the three existing solar irradiance plots with a new SATIRE-T2 chart that is extended using the Kopp/LASP reconstruction after 2008.

1) Absolute TSI: Kopp/LASP (1610-2018), Lean 2015 (1610-2014), CMIP5 (850-2000), LASP SIST (1978-2025)

Absolute TSI comparison of modern reconstruction, Lean 2015, and CMIP5

Native absolute scale, no +5 W/m² display shift. Legend labels now include both publication/source year and coverage range (for example: "Wu et al. 2018; 1610-2018").

2) Anomaly Comparison (1850-2000 baseline; includes LASP SIST 1978-2025)

TSI anomaly comparison over 1850 to 2000 baseline including LASP SIST

Anomaly-normalized view to compare shape without absolute baseline offsets, now including LASP SIST anomaly values through 2025.

3) Lean-Style Reconstructed Solar Irradiance (1610-2000 charted period)

Lean style reconstructed solar irradiance chart

Legacy reconstructed TSI chart from the existing solar reconstruction page.

4) SATIRE-T2 (1700-2008) with LASP SIST Extension (2009-2025)

SATIRE-T2 annualized with Kopp LASP extension

Legend now shows explicit periods: SATIRE-T2 (1700-2008), LASP SIST extension (2009-2025), and Maunder interval (1645-1715).

5) Requested Overlay: Panel-1 Blue/Green + Temperature-Solar Yellow

Panel 1 blue and green lines with yellow 11-year smoothed solar line

Blue and green are the absolute-series lines from panel 1. This panel is a diagnostic overlay for comparison against the temperature-vs-solar figure, not the restored NASA-style chart itself. Yellow represents the smoothed solar comparison line; treat temperature_vs_solar.png as the reference chart.
