| Summary: | Layers include: Land Surface Temperature daytime monthly median value 2000–2017, Land Surface Temperature daytime monthly sd value 2000–2017, Land Surface Temperature daytime monthly day-night difference 2000–2017. Derived using the data.table package and quantile function in R. We derived four standard statistics: (1) lower 2.5% probability (l.025), median (m), upper 97.5% probability (u.975) and standard deviation (sd). Updated long-term values for 2000–2022+ are pending. Includes also long-term trends (trend.logit.ols) which was produced by fitting regression models to de-seasonalized time-series as explained in this python tutorial. Basically models are fitted for each pixel and the model parameters are saved as images. For more info about the MODIS LST product see: https://lpdaac.usgs.gov/products/mod11a2v006/.

File naming convention: clm = theme: climate, lst = variable: land surface temperature, mod11a2.oct.day = determination method: MOD11A2 product, day time values for October, d = median value / sd = standard deviation / u.975 = aggregation/statistics method: 97.5% probability upper quantile, 1km = spatial resolution / block support: 1 km, s0.0cm = vertical reference: land surface, 2000.2017 = time reference: from 2000 to 2017, v1.0 = version number: 1.0, Processing steps are explained in detail at: https://gitlab.com/openlandmap/global-layers/-/tree/master/input_layers/MOD11A2 |
