# Dataset Summary
Contains hourly 2 meters of land (on-shore) air temperature data within grid areas of Thailand country. <br/>
Data is retrieved from [Corpernicus Climate Data Store](https://cds.climate.copernicus.eu/cdsapp#!/home) on [ERA5-Land hourly data from 1950 to present](https://cds.climate.copernicus.eu/cdsapp#!/dataset/10.24381/cds.e2161bac?tab=overview)
<br/>
Thailand areas in this context is **Latitude** = **[5.77434, 20.43353]** and **Longitude** = **[97.96852, 105.22908]** <br/>
For more details of data, you can refer to [ERA5-Land hourly data from 1950 to present](https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-land?tab=overview))
- Data Granularity: Hourly per Latitude/ Longitude
- Period: 01/Jan/2010 - 13/May/2023
- Temperature Unit: Kelvin
# Source Data
- Organization of the producer: ECMWF
# Data Creation
Below is an example of how to make data query using Python via [CDS API](https://cds.climate.copernicus.eu/api-how-to) in monthly requests. <br/>
``` python
import cdsapi
c = cdsapi.Client()
month_list = [str(num).zfill(2) for num in range(1, 13)]
day_list = [str(num).zfill(2) for num in range(1, 32)]
time_list = [str(num).zfill(2) + ":00" for num in range(0, 24)]
year_list = [str(num) for num in range(2000, 2022)]
for year in year_list:
for month in month_list:
c.retrieve('reanalysis-era5-land',
{
'variable': [
'2m_temperature']
,
'year': year,
'month' : month,
'day': day_list,
'time': time_list,
'format': 'grib',
'area': [
20.43, 97.96, 5.77,
105.22,
],
},
f'{year}_{month}_hourly_2m_temp_TH.grib')
```
Direct file output from API is in ```.grib``` format, to make it easy for futher analysis work, I have converted it to ```.parquet``` format.
To convert GRIB format to pandas datafram, you can use [xrray](https://github.com/pydata/xarray) and [cfgrib](https://github.com/ecmwf/cfgrib) library to help as below example snippet of code.
``` python
import xarray as xr
import cfgrib
ds = xr.open_dataset('2022_12_31_hourly_2m_temp_TH.grib', engine='cfgrib')
df = ds.to_dataframe().reset_index()
```
