DTM2000

See Orekit implementation here.

It is described in the paper:

The DTM-2000 empirical thermosphere model with new data assimilation and constraints at lower boundary: accuracy and properties S. Bruinsma, G. Thuillier and F. Barlier
Journal of Atmospheric and Solar-Terrestrial Physics 65 (2003) 1053–1070

This model provides dense output for altitudes beyond 120 km.

The model needs geographical and time information to compute general values, but also needs space weather data : mean and instantaneous solar flux and geomagnetic indices.

Mean solar flux is (for the moment) represented by the F10.7 indices. Instantaneous flux can be set to the mean value if the data is not available. Geomagnetic activity is represented by the Kp indice, which goes from 1 (very low activity) to 9 (high activity).

All these data can be found on the NOAA (National Oceanic and Atmospheric Administration) website.

The Tracker Component Library is a collection of Matlab routines for simulating and tracking targets in various scenarios. Due to the complexity of the target tracking problem, a great many routines can find use in other areas including combinatorics, astronomy, and statistics.

Recently, I ran into a very comprehensive MATLAB repository, which is very rare to my knowledge. Usually people find comprehensive packages in other languages, like Orekit in Java, GMAT in C++, many others in Python, and even one in Julia.
So, I decide to have a look at it and take nots here.

When you search “Excluding self-citation in Google Scholar” on Google, the first item is [By Brinxmat]. But unfortunately it does not work anymore, at least for me.

However, it gives me some insights and then I fiddling with Google Scholar a little bit. Now we have an easy solution.

This is the original citation link of one of my paper:
https://scholar.google.com/scholar?oi=bibs&hl=en&cites=17562392294963478550
This link actually works:
https://scholar.google.com/scholar?hl=en&as_sdt=0%2C31&sciodt=0%2C31&cites=8618462917299343813&scipsc=1&q=-author%3A"H+Peng"&btnG=

As you see, the trick is still on the query except that it has been much more complicated than what Brinxmat found in 2010.

So, the manual solution is to:

  1. Open your google scholar profile.

  2. Click the cited by link for one paper, and figure out the cites ID in the address bar. Like the number string 17562392294963478550 in https://scholar.google.com/scholar?oi=bibs&hl=en&cites=17562392294963478550.

  3. Paste the ID in the following link

    https://scholar.google.com/scholar?hl=en&as_sdt=0%2C31&sciodt=0%2C31&cites=17562392294963478550&scipsc=1&q=-author%3A%22H+Peng%22&btnG=

    and replace the author name H+Peng by your name, keep the plus sign.

  4. Done!

A little explanation:

  • After opening a cited by link, you will see a checkbox saying “Search within citing articles”, then check the box.
  • Then put -author:"H Peng" in the search box, then press Enter.
    (It is a short hyphen there, not dash. Pay attention to your input method.)
  • Then the above link address shows up.
