# AP2042 Course Materials
> ##### Course Name:
> ##### Course Number: AP2042
> ##### Lecturer:
> ##### Semester: 2022-Fall
## Week01
### Course will discuss about:
air → water
- air
- stratosphere → ozone hole
- troposphere → air pollution → health
- water
- ocean: salinity → density, weight
- fresh water → pH
理論探討過程中了解環境變化 → we need data!!!
data ↔ theory (through programming)
## Week02
### $CO_{2}$
grail → prevent devastatator
We will plot the figure with coding in this semester.
snow melting then bubble rising → snow turn into ice, then we can distinguish the year. → we can know the concentration of CO2
air be intefered by ocean water.
Atmosphere, hydrosphere, lithosphere, Cryosphere, Biosphere
SDGs
### Build graphical environment by 1chooo
``` vim
$ conda create --name atmEnv python=3.9.7
$ conda activate atmEnv
$ conda install -c conda-forge cartopy
$ conda install -c conda-forge netcdf4
$ conda install pandas
$ conda install -c anaconda xarray
```
## Week03
### Main Topic: $CFCl_{3}$
#### Battery
Bsttery is the most we care about now!!! → how to storage is difficult present.
city, urban/regional, global scales → modeling, data assimilation
ALE/GAGE/AGAGE, NASA(1994) (1987 Montreal protocal)
濃度隨時間改變上升,雖然氟氯碳化物排放多在北半球,但因為惰性,所以全球皆會受影響(空氣流動),梯度相同且一致。(不受物理方式(雲水、沉降)消失或者化學時間推進減少),排放過程持續進行。
global change → ozone → (butterfly)

$CH_{3}CCl_{3} + OH$
$CFCl_{3} + OH -> X$
Natural process -> balance(emit and absorb)
radiosonde, ozonesonde
* ppmv: part per million $10^{-6}$ -> concentration represent higher
* ppbv: part per billion $10^{-9}$
* pptv: part per trillion $10^{-12}$
CMDL/NOAA to graph the ozone changing

## Week04
Robot - Tesla (Boston Dynamic)
Why the temperature in Antarctica so low
平流層 2-D
Synoptic scale v ~ 10m/s, w ~1 cm/s
Convection W 3 ~ 5 m/s
we have theory -> we have to count
## Week05
## Week06
``` vim
```
## Week07
環保署資料
### PAHs - Polycyclie Aromatic Hydrocarbons
released into ecosystem from atmospheric emissions
medical
enviroment
戴奧辛致癌
if we use the data wisely, we can earn a lot of money.
## Week08
mid-term
## Week09
$CO_2$ lifetime long
The substance can't be discarded.
冬天結束我們可以觀測海冰跟雪的指標
IPCC evaluate report
$2.4 W/m^2$ bring us the huge changed.
get data is important to us.
有擾動過程,臭氧濃度上升

* [data](https://iagos.aeris-data.fr/)
* [Python plot the map](https://www.zhihu.com/question/33783546)

## Week10
壓力原理、浮力原理、理想氣體方程,地球參數
伴隨很多工程發展
空氣中 0 度一大氣壓 $2.7 * 10^{19}$ 透過理想氣體方程
生產過程中有廢氣,有很多化學物質 $CO_2$
將化學運用,讓方程式有意義
光化學,一階的反應,可以推倒大氣在時間,還有二階、三階。
## Week11
Last we week, we talk about Photochemistry reactions, we need the professional skillls with predictions and analysis. -> data(Fortran, Python)
Data bring results; **process?**
#### Mathematics
First order: $A \rightarrow B + C$
$\frac{d[A]}{d[t]} = -R[A]$
$\hookrightarrow {\frac{\partial [A]}{\partial t}} + \vee \nabla[A] = -R[A]$
$\frac{d[B]}{d[t]} = R[A]$
$\frac{d[C]}{d[t]} = R[A]$
#### Chapman Reactions
only four reactions 說明基數氧的形成
對流層內閃電會形成高溫的分解
$NO + O_3 \rightarrow NO_2 + O_2$
逆反應 光化分解產生臭氧
$O + NO_2 \rightarrow NO + O_2$
對流層頂溫度太低了
早在過往衛星便發現臭氧洞的問題
