In the previous step,I got some data about Broken Bow Reservior.But I don't know how to calculate them$(4)$ Select one reservoir in USA from DAHITI website that have in$-$situ water level data available from the USGS website.

$RM{S}^{}$

CC

$(5)$ Since in$-$situ data has higher temporal sampling than the DAHITI product $($derived from altimeter data$),$ select the in$-$situ data acquired at the same date of altimeter data acquisitions for comparison.

$(6)$ Remove the bias between the altimeter and in$-$situ time series: in other words,

$(7)$ Compute and report the RMSE $($root$-$mean$-$squared error$)$ and $($CC $($correlation coefficient$)$ after between the bias$-$removed altimeter and the in$-$situ water levels obtained from the previous step.

$(8)$ Plot the bias$-$removed altimeter time series on top of the bias$-$removed in$-$situ time series for visual comparison.

$(9)$ Add your own interpretation. $q,$

What to Submit $($MS Word or PDF file$)$ :

$*$ About the reservoir you chose

Altimeter time series before and after the bias removal $($in one time series, add a legend, add titles for $x-$ and $y-$axis, don't forget units$)$

In$-$situ time series from $(5)$ above $($i$.$e$.,$ acquired at the same date of DAHITI altimetry data$),$ before and after the bias removal $($in one time series, add a legend, add titles for $x-$ and $y-$axis, don't forget units$)$ longleftrightarrow pl $.$

Plot of the bias$-$removed altimeter time series on top of the bias$-$removed in$-$situ time series for visual comparison, from $(8)$ above $($in one time series, in one$)$ time series, add al $*$ legend, add titles for $x-$and $y-$axis, don't forget units$)$

Write down RMSE and CC you computed.

Your own interpretation of the results.
