在雁栖湖上课的时候并没有在周边玩好好逛过，本来想去滑雪场的但因为疫情也作罢了。朋友Y有空开车去郊区玩就叫上了我，恰好遇上某电影节[1]，因此路上有些拥堵。

虽然天气并没有很好，但是景色还是不错，能从室内出门散心还是很快乐的。此处放上一些本次的照片(均来自Y和他的另一位朋友Q)。

Veritas

法语

c’est la vie
这就是人生。

似乎很常见的句子，在很多电影里见过。最近突然发现自然卷的专辑也叫这个，以前没注意，还蛮有趣。

merci beaucoup

首先安利一下真理元素的这个视频

Single Event Upsets

A single-event upset (SEU), also known as a single-event error (SEE), is a change of state caused by one single ionizing particle (ions, electrons, photons…) striking a sensitive node in a micro-electronic device, such as in a microprocessor, semiconductor memory, or power transistors.

Xarray open_mfdataset without time dim

Xarray have a convenient method to open multi-dataset parallelly. However, sometimes time are encoded in the filename and are not in th .nc coordinate. So we need a method. For example, the dataset of my lab CAQRA[1] do this.

Stackoverflow [2]:

Create a function which adds a time dimension to a DataArray, and fill it with a arbitrary date:

1
2
3
def add_time_dim(xda):
    xda = xda.expand_dims(time = [datetime.now()])
    return xda

Then, pass this function to the preprocess argument when running the open_mfdataset functions:

1
data = xr.open_mfdataset(files, preprocess = add_time_dim)

Finally, fill the time dimension with my dates:

1
data['time'] = dates

Github [3]

I inspired also by an issue in Github and get the code below:
