Looking at JEMS data

In [1]:

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
import os
import datetime
import netCDF4 as nc
import seaborn as sns
import glob

import JEMS

from salishsea_tools import tidetools, viz_tools

%matplotlib inline

In [2]:

sns.set_style('darkgrid')

In [3]:

sdt = datetime.datetime(2014,10,27)
edt = datetime.datetime(2015,12,31)

In [4]:

grid_B = nc.Dataset('/data/nsoontie/MEOPAR/NEMO-forcing/grid/bathy_meter_SalishSea2.nc')

In [5]:

nowcasts= '/data/dlatorne/MEOPAR/SalishSea/nowcast/'

Dotted lines are mean +- 2 standard deviations.

In [6]:

figmap, fig = JEMS.compare_JEMS_model('ADM001', sdt,edt, grid_B, nowcasts,smin=25)

In [7]:

figmap, fig  = JEMS.compare_JEMS_model('ADM002', sdt,edt, grid_B, nowcasts,smin=30, smax=33)

In [8]:

figmap, fig  = JEMS.compare_JEMS_model('BLL009', sdt,edt, grid_B, nowcasts,smin=20, tmin=7)

In [9]:

figmap, fig  = JEMS.compare_JEMS_model('GRG002', sdt,edt, grid_B, nowcasts, smin=15)

Deep water is too fresh but, in general, the profiles have a similar structure.

In [10]:

figmap, fig  = JEMS.compare_JEMS_model('PSS019', sdt,edt, grid_B, nowcasts,smin=15, tmax=13)

These comaprisons look very good.

In [11]:

figmap, fig  = JEMS.compare_JEMS_model('SEQ002', sdt,edt, grid_B, nowcasts,smin=30,smax=34,tmin=5,tmax=10)

Is there something off with the salinity observation?

In [12]:

figmap, fig  = JEMS.compare_JEMS_model('SKG003', sdt,edt, grid_B, nowcasts,smin=10,tmin=6,tmax=15)

There is a lot of diurnal variability in the salinity at this station, at all depths. Are there rivers close by?

Summary¶

We haven't looked carefully at the stratificaiton in Puget Sound. There are many more stations that we could compare with.
Our model depths are sometimes a lot shallower than the observed depths. Even if we take into account the partial step correction, we are still typically shallower. But the bathymetry is super complicated and we have to make compromises!
Station GRG002 is most interesting to me because it is close to the Boundary Pass waters. We are too fresh at depth here. But, the stratitification profile is similar to observations for the 4 comparisons shown here.
Some of the JEMS data (2015) is marked as preliminary.
Too bad I can't get the SJDF001 stations...
