The Beat Goes On

On Sunday I posted about ongoing efforts to implement the GISS weather stations into the sea level change software model.

I now have it put in place along with the PSMSL and WPS seaport databases.

But, there are still integration issues to be worked out because the weather records begin in 1880 and proceed to 2016 (one month so far).

The other data sets may begin and end at other times, so integration requires synchronization.

Anyway, I said in the previous post:
I completed the downloading and preliminary implementing of the GISS databases.

They are now located within the Dredd Blog SQL database system.

Man, over a million months of weather data, geological, and flora data about those stations.

To be exact, there are 4,813,380 monthly GISS temperature records within 401,115 annual temperature records at 7,364 weather stations.

The really neato part is that I have associated them with the Dredd Blog Zone, quadrant, and sub-quadrant system.

So now I can fuse them with the tide gauge stations and seaports within a small area, and graph the sea level change, temperatures, and the impact those have on seaports in that area over the years.
(It Is A Lovely Day In The Neighborhood). The very next day, on Monday, the work of some scientists was published.

Their work concerned the same question (what impact does temperature change have on sea level change?).

They had been working for some time on the idea of combining temperature and sea level change data (Temperature-driven global sea-level variability in the Common Era).

Their effort was about knowledge "motivating the construction of a semiempirical model that relates the rate of GSL change to global mean temperature" (ibid, at p. 5).

I like their paper, except for the use of global mean average sea level and temperature to argue their points.

Regular readers know that I divide the globe up into small latitude and longitude sections called "Zones, zone quadrants, and zone sub-quadrants" (e.g. The Warming Science Commentariat - 2).

I have the databases set up in a way that I can focus on relevant tide gauge stations, seaports, and now weather stations, within a small area.

IMO, the use of temperature and sea level change data within those relatively small zones can better inform those who live and work in those zones.

Here are the zones that qualify with at least 1 PSMSL tide gauge station, at least 1 seaport, and at least 1 weather station:

Total Zones qualifying: 113
Total PSMSL (tide gauge) stations: 546
Total GISS (weather) stations: 4,024
Total WPS seaports: 2,852

Now, I am working on generating graphs which integrate the various types of data.

meanwhile ...

  1. 113 Zones! Is a lot of effort Dredd! Any plans to make SLC a data feed on something like Earth.nullschool.net? Once people's shoes get wet or 'their' ocean recedes, they'll begin to pay attention, you betcha! great work!

  2. The 133 out of 576 sub-Quadrants qualified because they have at least one of all three relevant entities.

    That is, at least 1 PSMSL tide gauge station, as well as at least 1 GISS weather station, and also at least 1 WPS seaport.

    I commonly call all of the 3 types of square areas "zones."

    However, technically there are only 36 "Zones" (e.g. "AA"), 144 "Quadrants" (e.g. "AA.NW", "AA.NE", "AA.SW", "AA.SE"), and 576 "sub-Quadrants" (e.g. "AA.NW.SE").

    That means each Zone has 4 Quadrants and 16 sub-Quadrants.

    Totalling 756 square areas around the globe (squares within squares).

    The sub-Quadrants vary from ~833 km. to ~1,107 km per side (833² = 693,889 km²) and (1107² = 1,225,449 km²).

    Very small compared to the GLOBAL km² ... nevertheless, most of those "zones" (sub-Quadrants) are missing a tide gauge station or a weather station, or a seaport, so they were not included in the list of 133 in this post.
