Effective Design of Profiling Float Network for Oceanic Heat-Content Monitoring

Figure 4

Modified sensitivity calculated as the product of the sensitivity values shown in Figure 2 and the square root of temperature error. The values are averaged over the upper 2000 m of the water column and within specified windows of time. The windows of time are (a) 0 years, (b) 10 years, (c) 30 years, and (d) 50 years (see Section 3.2 in the text for details). The units are in Kelvin.

(a) Adjoint  𝑇  *  weight at 0–2000 m depth (0-0 yr)

(b) Adjoint  𝑇  *  weight at 0–2000 m depth (−10–0 yr)

(c) Adjoint  𝑇  *  weight at 0–2000 m depth (−30–0 yr)

(d) Adjoint  𝑇  *  weight at 0–2000 m depth (−50–0 yr)
