1. Text Correction

There was an error in the original publication [1]. Thanks to valuable input from Dr. ZhongPing Lee, a typo was found in Charlotte Begouen Demeaux’s code computing K_d(λ)^Lee⁰⁵. This resulted in the values of K_d(λ)^Lee⁰⁵ used in the original paper being ≈12% lower than the corrected values. This difference was evenly spread across the range of K_d(490)^Lee⁰⁵ values; therefore, it does not affect the shape of the bias that was presented in this study. Therefore, the systematic overestimation of K_d(490)^float by K_d(λ)^Lee⁰⁵ is in the same range as the one by K_d(490)^NN, and this happens for very low K_d(490) values (<0.025 m⁻¹). Corrected values are presented in the paragraphs below. Please note that the changes have been marked in bold.

A correction has been made to Section 3.1 K_d(λ): Global Scale Match-Ups.

K_d(490)^Rrs retrieved from each of the algorithms generally followed the 1:1 line (Figure 3). The operational products (K_d(490)^NASA for MODIS and VIIRS, K_d(490)^ESA for OLCI) had the best statistical results for the VIIRS and OLCI sensors, with the lowest Bias, APD and RMSE for each sensor (Table 3), and K_d(490)^Lee⁰⁵ had the best results for the MODIS sensors. K_d(490)^NASA also retrieved the slope closest to one for all four sensors. K_d(490)^Lee⁰⁵ systematically overestimated K_d(490) at low K_d values (<0.025 m⁻¹) and had a few outliers for the MODIS sensors (not plotted on Figure 3 but used in statistics) that impacted its r-score. K_d(490)^NN had a slope furthest from one for the MODIS sensors and also showed a systematic overestimation at very low values (K_d(λ) < 0.025). The slopes were below one for all the sensors with a significant non-zero intercept. The K_d(490)^Rrs/K_d(490)^float ratio (Figure 3b) for low K_d values is larger for K_d values with a small zenith angle (≈10°), but for a given K_d value, a higher solar zenith angle resulted in a larger K_d(490)^Rrs/K_d(490)^float ratio.

The K_d(412)^float range of values is 0.0126–0.7 m⁻¹ (Figure 1 and Figure 4). The operational products are not computed at 412 nm and we therefore only compare K_d^Lee⁰⁵ and K_d(490)^NN to K_d(490)^float. K_d(412)^NN performed significantly worse than K_d(412)^Lee⁰⁵ for the MODIS-Aqua, MODIS-Terra, and OLCI-S3B sensors, with a lower r-score and a higher bias, APD, and RMSD for all sensors (Table 4). For OLCI-S3A, K_d(412)^NN performed better. The slopes are closer to one for each of the sensors than at λ = 490 nm while still showing a systematic overestimation for small K_d(412) < 0.026 values (Figure 3b), along with a significant non-zero intercept.

Both K_d(412)^Lee⁰⁵ and K_d(412)^NN had a lower APD at 412 nm than at 490 nm for all three sensors; however, K_d(412)^NN exhibited a larger RMSD. The slope is closer to one (all are >0.91). The ratio K_d^Rrs/K_d^float was closer to one at 412 nm than 490 nm (Figure 4).

A correction has been made to Section 3.2 K_d(PAR): Global Scales Matchups

The number of matchups between sensors-derived and floats-derived K_d(PAR) was 832 for MODIS-Aqua, 944 for MODIS-Terra, 1402 for VIIRS-SNPP, 613 for VIIRS-JPSS, 155 for OLCI-S3A and 227 for OLCI-S3B (Figure 5) resulting in a total of 4173 matchups between float and satellite. For all sensors, there was an underestimation for small values: K_d(PAR)^float < 0.038 m⁻¹ for K_d(PAR)^Morel and K_d(PAR)^float < 0.048 m⁻¹ for K_d(PAR)^Lee05 representing 11% and 20% of the full dataset, respectively. For those values, independent of the sensors, K_d(PAR)^float < K_d(PAR)^Rrs, with the ratio increasing as K_d(PAR)^float decreased (Figure 5b). The regression slopes are <1 for both algorithms, and there was a significant intercept for both of them (Table 5).

K_d(PAR)^Morel had a lower bias, lower APD, lower RMSD and a higher r than K_d(PAR)^Lee05 (Table 5). It also had a slope closer to one. For high values, K_d(PAR)^Lee05 > K_d(PAR)^Morel, whereas for low values, K_d(PAR)^Morel > K_d(PAR)^Lee⁰⁵ (Figure 5). The biggest discrepancy between the two algorithms occurs when the Solar zenith angle is low (<20°), but for a given K_d(PAR)^float value, the higher the solar zenith angle, the bigger the difference.

A correction has been made to Section 3.3: Variability in Performance between Satellite Sensors (paragraph 1 and 3).

We performed a Kolmogorov–Smirnov (K-S) test to assess whether the distributions of K_d^Rrs (λ) retrieved by a given sensor using different algorithms were different. The K-S test indicates whether the K_d values retrieved by different algorithms have a different distribution within a given confidence interval (here 5%). The distributions of K_d(490)^NN vs. K_d(490)^Lee⁰⁵ retrieved by the OLCI-S3A sensor were not statistically different from each other (Table 3), whereas, they were different for the other sensors. The distribution of K_d(490)^Lee⁰⁵ vs. K_d(490)^NASA^/ESA was statistically different for all sensors as was the case for the distribution of K_d(490)^NN.

For all three algorithms tested, the only ones that had a similar distribution were for the K_d(490)^NASA^/ESA algorithm of the VIIRS-SNPP/OLCI-S3B sensor pair, the K_d(490)^Lee⁰⁵ algorithm between the OLCI-S3B/VIIRS-SNPP and for the OLCI-S3B/VIIRS-JPSS pairs. All other sensor pairs had statistically different distributions.

A correction was made to paragraph 3 of Section 3.4: Regional Analysis.

No obvious biome-based bias in algorithm performance was observed (Table 6), with biome 9 having the lowest bias and RMSD across all three algorithms but having slopes significantly different from one. Similarly, biome 18 had slopes close to one for K_d(490)^Lee⁰⁵ and K_d(490)^NN but lower r than other biomes, such as biome 19. Note that some biomes (e.g., 6, 8, 10, 12, and 14) had a low number of matchups and limited dynamic range resulting in (non-significant) negative slopes and r.

A correction was made to the numbers presented in Section 4.1: Observed Biases in K_d.

All four algorithms had a slope < 1 at λ = 490 (Table 3) because K_d(490)^Rrs > K_d(490)^float at small K_d values. This overestimation of K_d(490) effectively leads to an underestimation of the depth to which light penetrates in the water column, potentially resulting in an under-estimation of heat transfer to depth and other depth-derived products from K_d(490). On the other hand, for K_d(490) > 0.1, K_d(490)^Rrs < K_d(490)^float (Figure 3). This underestimation of K_d will result in the overestimation of K_d(490)-derived products. The overestimation at small values is also found at λ = 412, with a systematic overestimation for K_d(412)^NN and K_d(412)^Lee⁰⁵ at values < 0.025 (Figure 4). However, there is no persistent underestimation for larger K_d(412) values (Table 4).

It is also relevant to note that there is a strong relationship between K_d(490)^float and R_rs-retrieved Chl a (r-score of 0.84 over the full matchup dataset), which is only slightly lower than the correlation score between the full K_d(490) ^float and K_d(490)^Lee⁰⁵ (0.89 over the full dataset) which asks the question about redundancy between the offered Satellite L2 products.

A correction was made to the numbers presented in the third, fourth and sixth paragraph of Section 4.2: Limitation of Datasets Used to Train Empirical Algorithm

We found the slopes of the regression between algorithm and float to typically be significantly less than one. If the regression intercept is forced to zero, the slope of K_d(490)^Rrs vs. K_d(490)^float is closer to one, regardless of algorithm or sensors (Table A3). It ranges from [1.03−1.17] for K_d(490)^Lee⁰⁵, [1.15−1.30] for K_d(490)^NN, and [0.98−1.14] for K_d(490)^NASA^/ESA. It is apparent that the small values that are not sufficiently represented in the original range drive the slope offset we found.

Overall for K_d(490)^Lee⁰⁵, 74% of the values were within ±25% of K_d(PAR)float, 49% for K_d(490)^NN, and 80% for K_d(490)^NASA^/ESA (Figure 3b). Therefore, the performances of the algorithms were significantly lower than on the original datasets they were based on, indicating that they could be improved. At 412 nm, 64% of K_d(412)^Lee⁰⁵ were within ±25% of K_d(412)^float versus 65% for K_d(412)^NN.

Similarly, K_d(PAR)^Morel and K_d(PAR)^Lee⁰⁵ were designed using available in situ databases (NOMAD, among others mentioned above) or the IOCCG dataset, resulting in similar biases to those observed for K_d(412) and K_d(490). Clear-water biases are more important than for K_d(λ): 53% of K_d(PAR)^Lee05 values were within ±25% of K_d(PAR)^float and 20% of were consistently overestimated (K_d(PAR)^float < 0.048). Some 53% of the K_d(PAR)^Morel were within ±25% of K_d(PAR)^float, and 11% were systematically overestimated (K_d(PAR)^float < 0.039). Note that the overestimation of K_d(PAR) was first pointed out by the authors of [2].

2. Error in Figures/Tables

In the original publication, the previously mentioned error in the computation of K_d(λ)^Lee05 led to mistakes in the presented Figures/Statistical Tables. The corrected Figure 3, Figure 4 and Figure 5 and Table 3, Table 4, Table 5 and Table 6 are shown below.
