Monthly Tip Data

These Comma Seperated Variables (CSV) files contain the time of each tip for a given gauge over and entire month. The first line contains the gauge id, longitude and latitude. The next line contains the column headers, followed by the actual data. These files are easily imported using Excel or python Pandas.

To read into python Pandas, do the following: 

	import pandas as pd
	f = 'PIERS0029_2023_09_tips_A.csv'
	df = pd.read_csv(f, skiprows=1)
	df.index = df['Date']
	df = df.drop(columns=['Date'])
	df
