Description

I'm new to the Monetio package, so I'm working through the practices examples on the ARL website. When I run this code (see below), I get this error message:

import numpy as np
import pandas as pd
import monetio as mio ##observations for MONET
import matplotlib.pyplot as plt
import seaborn as sns ##using this for better color palettes
import cartopy.crs as ccrs ##map projections
import cartopy.feature as cfeature ##poltical and geographic features

sns.set_style("ticks") ##plot configuration
sns.set_context("talk") ##plot configure for size of text

dates = pd.date_range(start='2004-01-01',end='2004-12-31')
df = mio.aqs.add_data(dates,daily=True,param=['VOC','OZONE'], download=True)

from numpy import sort

for i in sort(df.columns):
print(i)

from monet.util import tools

new = tools.long_to_wide(df)
new.head()

new.dropna(subset=["ISOPRENE"]).siteid.unique().shape

for i in sort(new.columns):
print(i)
new.describe()

new.index = new.time
new["OZONE_ppb"] = new.OZONE * 1000
print(new.OZONE_ppb.mean())

f, ax = plt.subplots(figsize=(10, 4))
new.ISOPRENE.resample("D").mean().plot(ax=ax)
plt.show()

ValueError: Metadata mismatch found in from_delayed.
